How To Update Javascript

Considering how advanced our browsers have become, there’s still a lot of things to take care of. It seems like every other day, we’re forced to update different plugins or find replacements for those that have been broken. One such annoyance is JavaScript – it’s required by numerous sites to run, and it updates frequently.

In this guide, we’ll explain how to install the latest version of JavaScript on your system. Luckily, it’s a quick and easy process, so you shouldn’t encounter any trouble.

Step 1 – Go to the Java Website

First of all, we have to visit the Java site. Java and JavaScript are different things, but they’re both available from the same place. Click the Download link at the top of the page and you’ll be redirected to the right location based on your operating system.

Next, click the Agree and start the free download button. You might see a message like the one below based on your browser. This just means that recent versions of Chrome have dropped support for Java applets and Microsoft Silverlight.

Step 2 – Download and Install JavaScript

When you click the button, a file will start downloading. When it’s done, click it to start the installation wizard. If you’d like to change the location, check the box at the bottom, otherwise, just click Install.

The entire installation process should only take a minute or so. Just be patient!

If the installer finds older versions of Java on your system, you’ll be asked if you’d like to remove them. We recommend doing this because as the wizard notes, they can be exploited by attackers looking to compromise your system.

Once any older versions have been removed, you’ll see a popup that mentions your currently installed version Java (and hence, JavaScript). There’s also a little information here about the next planned update, should you wish to update again in the future.

Step 3 – Test the New Version

Now that you’ve installed the latest version, restart your computer. Next, open your browser and visit a site that heavily uses JavaScript. If everything works as intended, you should see your currently installed version. That’s really all there is to it!


If your JavaScript needs to be updated, there’s no need to panic. The entire process takes less than five minutes and once it’s done, you’re probably good for another few months at least. As an added bonus, you’ll be able to visit websites that use all the latest, flashiest animations. What’s not to like?

Now that you know how to update javascript, take the time to read our guide on how to fix Java virtual machine launcher error. This guide will help you resolve the underlying issues. Read it right here!
