What Is JavaScript & What Does It Do?

In this video, the video2brain creator walks you through what JavaScript is and what it does, including a few examples.

What is JavaScript, the creator asks- he articulates that Javascript is not Java.The fact that they are each well-known programming languages with very similar names is regrettable since they genuinely have absolutely nothing to do with each other. But like Java, Javascript is a programming language and in all likelihood probably the most popular and commonly used on the planet at this time.

So what does JavaScript do? The vlogger says that JavaScript is a programming language- therefore what that effectively means is that it enables you to program, or ‘boss’ around the internet.

You can use it to program internet browsers. You may also utilize it to program servers. What exactly that means, he explains, is it allows things in the browser that have been formerly, in the early days of the internet typically static. The way it traditionally was, your web-page would download, it would load some images, and really the only motion or changes which you might observe would be animated gifs, but JavaScript enables you to produce very robust interactivity.

Nowadays, JavaScript is taking over a bunch of areas of interactivity that perhaps five or six years back were completely carried out with Flash.

But JavaScript has the benefit of functioning on many contemporary mobile devices. So, if you’re accessing an internet site on a phone or other kind of mobile computing platform, and you observe interactivity on screen, where elements are moving about or there are graphic effects it’s probably being created via JavaScript.And if you truly desire to see some of the things that JavaScript does try out disabling JavaScript in your internet browser and browsing the internet and observe what happens- lots of things, vanish or break or they function in an ideal way.

Stack Overflow Insight

Over in Stack Overflow, a user posted a question regarding the Backbone.js source code . He pasted the following line of code:validObj[attr] = void 0;

He was wondering what void 0is and what exactly the purpose was of using it there.

A developer explained that ‘void’ is a prefix keyword which takes one argument and will always return ‘undefined’. He says that for development purposes, in a perfect world, you’d be able to securely employ use “undefined:” on its own- it’s ostensibly much simpler to understand than “void 0”.

Unfortunately, however, the problem with using “undefined” is that ‘undefined’ is not a reserved word because apparently it’s the property of the global object [wtfjs]).

Because ‘undefined’ is a permissible variable name, you could capriciously assign it a new value, which would cause all sorts of disorder.

Try the fixes above to fix this common internet browsing error. It’s a common issue and usually can be resolved without much technical acumen.
