11/4/2023 0 Comments Javascript programs for beginnersSome developers believe that it’s important to understand the main rules of JavaScript instead of relying only on shortcuts from JS frameworks and libraries. That’s thanks to the development of the ECMAScript spec – standardized specification of a scripting language developed by Netscape. But now, relying on external libraries is no longer needed. In the past, a developer would often default to using jQuery. Vanilla JavaScript refers to using plain JavaScript to build a site without any libraries.Ĭreated as a joke to prove a point in 2012, Vanilla JS shows that plain old “vanilla” JavaScript often works perfectly well without the use of additional JS frameworks or libraries.ĭevelopers used to bypass plain JavaScript for several tasks – from making code behave consistently across browsers to offering more features than JavaScript could back then. Some examples of popular JS libraries are MooTools, YUI, jQuery, Prototype, and Dojo. You can even build a WordPress site with these libraries. This allows you more time to code the less common elements of the site that don’t have a simple plug-in fix.Ī JavaScript library is a collection of pre-written JS code that makes developing JS-based apps easier.Ī JavaScript library contains a variety of objects, functions, and methods to do practical tasks on a webpage or JS-based app. Instead of making it from scratch, you can simply make adjustments to the framework. Here’s an example: you’re making a standard JS photo carousel on a website, so you use code from a framework to give you that feature. Instead of coding every part of the site completely by yourself, you simply use common website features from the framework. It’s a set of code libraries that give developers pre-written code to use for common programming elements and tasks – a template for building websites or apps.Ī framework makes it much easier and more expedient to build sites. JavaScript is also responsible for interactive online forms and photo slideshows.īasically, JavaScript is used to make and control any element on a website that moves refreshes, or changes on without you having to manually reload the web page.Ī JavaScript framework is a template. Animated graphics have become an expected website feature. People have grown to appreciate not having to type out every letter and word themselves with JS’s autocorrect text suggestions. JavaScript is used to “automate and animate.” Anything created with JS tends to run smoothly on a wide variety of different machines. JS also offers lower overheads because of being well-optimized. It’s also versatile and you can use JS for pretty much anything thanks to its extra features like libraries that are full of functions. This means that JS can be executed as soon as it’s written, without compiling – so, faster prototyping and less headache. JS is an established, high-level language that requires no compilation. But programmers use it for many more functions: JS has many uses: you can use JS to apply complex elements on a web page - like interactive maps and animated graphics. The script was renamed to hitch up to the popularity of Java, another popular programming language in those days. JavaScript was developed in the early 90s to allow a browser to respond to user commands, and it was first known as LiveScript. Because of its longevity, there are many resources available for new users, and a lot of existing expertise. JS is a top programming language that has been used in one form or another for over thirty years. JavaScript (often shortened to JS) is a programming language that is one of the major technologies of the internet, along with HTML and CSS. You may still be wondering what JavaScript is all about, and there’s much more to learn, so let’s talk about it. Did you know that as of 2022, 98% of websites use JavaScript for webpage user behavior on the client side?
