Suggested December 2023 How To Compare Two Dates With Javascript?
In this tutorial, we will learn to compare two dates with JavaScript. The date is also one of the data types in JavaScript, and most developer works with it while developing applications.
Let’s understand the need to compare the date with a real-life example. Most of you are using the internet data, and the company sends a message like “2 days left for your data pack validity.” Also, users can see the same notification in the application of network provides. This all happens due to the date comparison.
Here, we have two various approaches to make a comparison between the two dates.
Comparing the Total Millisecond of Two DatesWhen we create the new date using an object of the Date() class. We use the getTime() method to get time in milliseconds. The getTime() method returns the total number of milliseconds from the 1st Jan 1970, when the Unix epoch started. We can compare the total number of milliseconds and decide whether the date is the same.
SyntaxUsers can follow the syntax below to compare the total milliseconds of two dates.
let date1 = new Date(); let date2 = new Date(2012, 11, 21); if ( date1.getTime() < date2.getTime() ) { } else { } ExampleIn the example below, we have implemented the above approach. We have created the two new objects of the Date() class and compared the total number of milliseconds using the if-else statement. Users can see the result of the comparison between various dates in the output.

Compare two dates using chúng tôi diff() methodJavaScript contains various libraries; one of them is chúng tôi which is used to manage the date and time. chúng tôi has a diff() method, which gives the difference between two dates in years, months, days, hours, minutes, seconds, milliseconds, etc. We can use the second unit in our case to find the difference between the two dates.
Before using the chúng tôi methods, make sure to include chúng tôi or add CDN to the tag of the HTML code.
SyntaxYou can follow the below syntax to use the diff() method of Moment.js.
let date1 = moment(); let date2 = moment("2024-11-21"); let difference = date1.diff( date2, "seconds" ); Parameters
date1 and date2 is the two date for which we need to make comparisons.
seconds − It is a unit of time in which we need the difference. Users can also use the minutes, hours, etc.
ExampleIn the example below, we have created the two date objects using the moment(). We have applied the diff() method to two objects to compare them and render the message in the output according to whether the difference is the same, positive, or negative.

How To Easily Compare The Specifications Of Two Phones
Google Pixel or Samsung Galaxy S7? Motorola Moto G 3rd Generation or iPhone 6? For a newcomer to the smartphone world or an expert that can’t remember every detail of every phone on the market, finding the right smartphone can be hard. Even worse, people will be attracted to different specifications of a phone. While some will favour huge processors and masses of RAM, others will want a smaller, sleeker phone to easily put into pockets and bags. Finding the details that correspond to what you want and making the correct purchase can be daunting.
Of course, there’s always the solution of visiting a manufacturer or distributor’s website and collating information about each phone you’re interested in. Given how big an industry smartphones and tablets are these days, however, you’ll find there are a lot of websites out there willing to trawl through all the boring details and pluck out the important parts. All you have to do is enter the phone names, and these websites will do all the hard work for you. Here are a few great examples we’ve found.
GSM ArenaGSM Arena is a very useful website when it comes to deciding which smartphone to buy. As well as comparing phone specifications for you, GSM Arena features articles that take new phones and pits them against one another over certain desirable attributes, such as camera quality. It’s also a good place to keep on top of new phone releases and check their specifications.
Phone ArenaPhone Arena has a similar name, but it’s good for its own merits. It, too, features news on the latest phones while also detailing important updates for very popular apps. You can look up the specifications of a particular phone where you can see if the phone has a fingerprint locking device, if it supports dual sim, or even if it’s deemed “lightweight” by Phone Arena.
If the size of the phone is a big factor for you, you can also use the size comparison tool. First, calibrate the website by selecting either a phone you already have or the “credit card” option. You then match your real-life item to the picture the website shows you. Once done, the website knows how to scale pictures to your monitor’s resolution. This means it can show you exactly how big each phone will be in real life. Very useful!
Sizing Up The CompetitionWith phones constantly being released, it can be very hard to keep on top of every phone’s specifications. Thankfully, these two websites will help you compare the phones you’re interested in so you can better find the phone that’s right for you.

Compare Two and Match Columns in ExcelIn this article, we will learn about Compare Two Columns in Excel for Match. Excel is the most potent tool on the planet, and we all will agree with this fact. We can do almost everything using Excel when it comes to data analysis. It is not only a tool that allows you to store the data but more than that. When comparing and matching different data sets or, for that sake, different columns, we have several options. Comparing two or more columns in Excel for Matches is also a task for every data analyst. In this article, we are going to see different methods using which we can Compare Two Columns in Excel for Match.
What is Comparing Two Columns in Excel for Match? Compare Two Columns for Match (Examples)We will discuss some methods to compare two columns for matches.
You can download this Compare Two Columns for Matches Excel Template here – Compare Two Columns for Matches Excel Template
Examples #1Consider the data shown in the screenshot below, which includes different text values.
We can use the simplest method to check whether two of the columns match. Follow the steps below:
Step 1: In cell C2, start initiating the formula using equals to sign (“=”). You can use your keyboard button for the same.
Step 2: Since we wanted to compare the value present in cell A2, use A2 as the first argument under C2 after the equals sign.
Step 3: Now, we want to check if the value in A2 matches the value in B2; for that, use =B2 as the next argument. The entire formula will read as =A2=B2.
This is a logical formula that checks whether the value present in cell A2 is exactly matching with the value present in cell B2. If both values match, then it will return Boolean output TRUE. If both values don’t match, it will return Boolean output FALSE.
Now, drag the formula across all the working cells and see the output as shown below:
You can see some of the cells will match each other from both columns, and some will not. This is because, for output in C2, A2 has the value “Sweets”, whereas the value in B2 is “sweets”. Same as with the 4th output where A4 has the value “Google” and B4 as “Google”. Etc.
Note that this criterion for matching does not consider whether the text is in upper or lower case.
Sometimes extra spaces allow the text not to match using the equality operator. For Example, see the fifth row where two strings look exactly similar and should match each other. But the result is FALSE because we have an extra spacing at the end of cell B5. You can validate this by using the Len function as well.
Examples #2Now, we will see a different method where we will use a conditional IF statement to check whether two of the columns have matches. Follow the steps below.
Sometimes, just getting values as TRUE/FALSE might not be a good representative when we are comparing two columns for matches. Having a proper phrase that can let you know whether the data matches or not matching will be helpful in such cases. Let’s create a custom formula that works in our favor using a conditional IF statement.
Step 1: Consider the same example as the previous one. In cell C2, initiate a formula using a conditional IF statement as shown below:
Step 2: The first argument under conditional IF needs a logical test. In our example, we need to check whether two columns have matching values; therefore, we can use A2=B2 as a logical test under the IF statement. See the screenshot below:
You need to use a comma as a separator to separate multiple arguments of the IF statement.
Step 3: Now, we need to specify the value for the argument [value_if_true]. This value will be reflected in cell C2 if the logical test has output as TRUE. We will use the keyword “Matching” as a value for this argument.
Step 4: We must specify a value for the argument [value_if_false] on similar lines. This value will be reflected in cell C2 if the logical condition has output as FALSE. We will use “Not Matching” as a value for this argument.
Don’t forget to use the double quotes within which the values should be added. Otherwise, there would be an error with the formula.
Step 5: Use closing parentheses to complete the formula and press Enter button to see the output.
You can see the value we are getting under C2 is “Not Matching” because the text in the two columns does not match.
Step 6: Drag the formula across the rows to see whether the two columns have matching values with each other or not.
These are the two methods using which we can compare two columns in Excel for matches. We will end this article here and have some points to be remembered for you guys on the same.
Things to Remember
You can use the equality operators like we compare two values in general mathematics. If the values match, it will return TRUE as output; if values do not match, it will return FALSE.
The equality operator doesn’t count the case of the text. Ex. DUBAI and Dubai are all the same for this operator.
We can customize the results by simply using a conditional IF statement to get a decent message for matches and non-matches instead of TRUE and FALSE.
We can compare data with numeric or Mixed values from two different columns for matches on similar lines.

Having the two-step verification system set up on your Telegram account is a great way to keep it safe. It lowers the probabilities of you losing your account. But, it does require that you introduce a pin you should have memorized. But, sometimes you forget what it is, or you want to change it to one that’s easier to remember.
Please keep reading to see how you can change your two-step verification pin when you know what your current pin is and when you’ve forgotten it. So, there’s no need to panic if you forgot your pin since it’s possible to recover it.
How to Create a New Two-Step Verification Pin on TelegramTo create your new pin, tap on the three-lined menu at the top left of your display. Once you’re in Setting, swipe down to the Settings section and tap on the Privacy and Security option.
On the next page, towards the bottom, you should see the Two-Step Verification option. Type the current password, and you’ll have access to three options: Change Password, Turn Password Off and Change Recovery Email.
Tap on the change password option, and you’ll be asked to enter the new password twice. Once you complete those steps, you’ll see a cute celebration emoji letting you know that you’re done. That’s all you have to do to change your two-step verification password.
If you disable the password, you turn off the two-step verification altogether. The next time you want to enable it again, you’ll have to start over.
You’ll be asked to enter info such as your new password (twice to confirm), Recovery Email, and enter the code sent to your recovery email. If you happen to forget your password, here’s where your recovery email comes in handy. Telegram will send you a recovery code to the email you added when you first added the two-step verification.
Enter that code where Telegram indicates, and you’re good to go. If what you need to do is change your Telegram passcode lock, that’s a whole different story.
How to Create and Change a Passcode Lock on TelegramAs long as we’re on the topic of Telegram security, adding a passcode lock to your Telegram account is a good idea. That way, you’ll prevent anyone you haven’t given permission to from seeing your conversations. To protect your Telegram account with a passcode, tap on the three-lined menu option at the top left.
Once you’re in settings, tap on Privacy and Security. Under the Security section, tap on the Passcode Lock option.
If it’s your first time setting it up, you’ll be asked to introduce a pin you’ll use to access Telegram. If what you want to do is change it, in that case, you’ll need to tap on the Change Passcode option.
You’ll be asked to enter your new pin twice, and you also get a celebrating emoji at the end. As long as you’re in the Passcode lock settings, there are other changes you can make. For example, if you ever want to take a break from having to enter a passcode, you can disable it, or you can unlock it with your fingerprint.
You can also decide how much time needs to pass before auto-lock kicks in and if you want to show the app’s content in Task Switcher.
ConclusionThe more security you can add to any account, the better. You never know when that security setting might actually save it. By enabling two-step verification and locking your Telegram account with a passcode, you’ll have one less thing to worry about.
How To Set Up Two
Two-factor authentication may not be as sexy as the latest Android phone, but the technology is capturing news headlines, and deservedly so. Last week, Microsoft began rolling out this security tool for its some 700 million Microsoft Account users. Tuesday Wired reported Twitter is working on two-factor authentication as well.
It’s a security feature that could have stopped hackers at the gate before they seized control of the Associated Press Twitter account, and it’s something you should be using to protect your own online accounts, wherever it’s available.
So how does two-factor authentication work? In a nutshell, it requires not one but two pieces of privileged information before granting access to an online account.
Let’s say you’ve already set up two-factor authentication for your Google account, and now a hacker halfway around the world is trying to break into your Gmail. He has your email address and even your password, but he doesn’t have the second element of the authentication process. In the case of Google accounts, the second element is a unique security code that’s sent directly to your cell phone via text messaging.
In essence, two-factor authentication requires something you’ve committed to memory (your password) and something you have in your pocket (your phone).
If two-factor authentication sounds like kind of a pain, well, it is. Turning on this feature is a really easy way to make life harder for yourself, as you’ll need to spend extra time to prove your identity every time you log into a protected account from a new piece of hardware. Nonetheless, this level of authentication makes it much harder for hackers to seize control of your accounts.
Do you have a Google account and a smartphone? Then you should have two-factor authentication enabled.
Getting started also requires a little legwork on your part. Most major sites and services offer two-factor authentication as an optional security feature, so you need to log into your various accounts and dig around in the security settings to find it.
Google and Facebook have offered two-factor authentication as an optional security measure since 2011. Dropbox started offering it last year, and Apple iCloud got two-factor authentication in March. Microsoft is late to the party but now has it, and Twitter’s version of the technology can’t come soon enough.
For the sake of brevity I’m going to run down the two-factor set-up process for the Big Three social networks as well as my favorite remote storage services. But you should duplicate this process across every site and service you use that offers two-factor authentication. And if it seems like a lot of different systems to manage, don’t worry—there’s an app for that.
Start with GoogleGoogle makes two-factor authentication simple enough, but it can be very frustrating to configure if you log into Google across multiple devices. To get started, log into your Google account and navigate to the Security section of your Account Settings page.
Google offers a plethora of services across multiple devices, so it’s apropos that it offers a similar plethora of options for configuring two-factor login authentication.
You can also generate one-time use codes that you can write down and save for times when you want to log into Google in the absence of cell service. Generate five or ten of these codes, and keep them in your wallet for emergencies. Also consider downloading the Google Authenticator app for iOS and Android if you don’t want Google sending you text messages every time you check your mail from a new computer.
It’s simple to use, and can generate codes for any authentication service that employs the TOTP (Time-based One-Time Password) algorithm, including Facebook and Dropbox. I recommend setting it up to do so if you’re going to be enabling two-factor authentication on other services, but be aware that this will make it very difficult for you to log into those services without your phone. If your phone is lost or stolen—or if you just accidentally delete the authenticator app—it’s possible to download a fresh version and re-authenticate across every service you use, but it’s a real pain.
Facebook is easy by comparisonWhat we call two-factor authentication Facebook calls Login Approvals, and it works great.
To get that code you’ll need to either download a mobile authenticator app that generates codes every time you log in, or give Facebook your cellphone number so it can send you authentication codes via SMS. I recommend going the authenticator app route. It’s simple to use, and you don’t have to wait for Facebook’s servers to text you your code. Plus, you can also add a cellphone number as an additional backup if the app fails to work.
In its mobile app, Facebook built in a neat Code Generator feature that generates TOTP codes for your account, but you can use any old TOTP authenticator app if you’re willing to subvert Facebook’s setup process. If you’re using Google’s mobile authenticator app to manage two-factor authentication across multiple services, for example—which is a great idea—you can set it up to provide authenticator codes for your Facebook account too.
Microsoft is finally catching upYour Microsoft account covers your Outlook inbox, your Xbox Live profile, your Windows Phone, and more. Improve security across the board by switching on two-factor authentication in the security section of your Microsoft Account summary page. You can set it up so Microsoft will send security codes to either an alternate email address or your smartphone via SMS, unless you prefer to download an authenticator app that will generate security codes for you. Windows Phone users can download Microsoft’s own authenticator app from the Windows Store, but everyone else can just use any authenticator app that supports the One-Time Password algorithm.
Scan this blob of code with your authenticator app and you’ll be able to generate authentication codes with your phone no matter where you are.
For simplicity’s sake, I recommend using the aforementioned Google Authenticator app on iOS and Android. Use the app to scan the barcode that Microsoft provides you during the two-factor authentication process and it will generate codes for your Microsoft account as well.
And you don’t need to stop there—I expect Twitter will have its two-factor authentication system in place before summer rolls around, and there are plenty of other sites and services that already offer similar security systems. Dropbox, LastPass, Box, and even Amazon Web Services support two-factor, as do many banking services. Locking these accounts up with two-factor authentication adds another layer of security to your digital life, one that can be unlocked only with the smartphone in your pocket.
