Description

JavaScript is a scripting or programming language that allows you to implement complex operations on web pages – whenever a web page does more than just sit back and display static information that you can view – display updates real-time content updates, interactive maps, 2D animations/ 3D graphics, rotating video jukebox, etc. – you can bet javascript can be involved. This is the third layer in the layer cake of standard web technologies, two of which (HTML and CSS) we have covered in detail in other parts of the tutorial.

JavaScript (JS) is a lightweight, compiled, or just-in-time compiled programming language with first-level features. Although it is best known as a scripting language for web pages, many non-browser platforms also use it, such as Node.js, Apache CouchDB, and Adobe Acrobat. JavaScript is a robust, type-oriented, multi-instance, single-string language that supports object-oriented, dynamic, and declarative types (eg, functional programs).

Reasons to learn Javascript

JavaScript is a MUST for students and professionals who want to become good software engineers, especially when working in web development. I will list some of the benefits of learning JavaScript:

JavaScript is the most popular programming language in the world and that makes it a great choice for programmers. Once you learn JavaScript, it helps you create great front-end and back-end software using various JavaScript-based frameworks like jQuery, Node.JS, etc.

JavaScript is everywhere, it is embedded in modern web browsers and so to learn JavaScript you don’t need a special environment setup. For example, Chrome, Mozilla Firefox, Safari, and all the browsers you know today support JavaScript.

JavaScript helps you to create beautiful websites very quickly. You can use control panel to give your website a look and feel and give your users the best graphical user experience.

The use of JavaScript has now spread to mobile app development, desktop app development and game development. This opens up a lot of possibilities for you as a JavaScript programmer.

Due to the high demand, there is a lot of job growth and high salaries for people who know JavaScript. You can browse various job sites to see how JavaScript skills are available in the job market.

The advantage of JavaScript is that you will find many methods and libraries that can be used directly in your software development to reduce your time to market.

Advantages of JavaScript

JavaScript works on the client side

When you use a website, when you want to interact, for example clicking a button, you send a request to the server that is processed and in return you get a response. If you click on a link within a Wikipedia article, the page will load and you will be redirected to a new article/reading. However, you must notice that when you post a status update on Facebook, the entire page doesn’t load anymore. Or when you are filling out a form, sometimes you are immediately told about some of the mistakes you have made. All this is possible thanks to JavaScript.

There is no need to send a JavaScript code snippet to the server side to be processed. This saves load on the server side. The JavaScript code of the website is processed using the resources of the user’s system. Thanks to the configuration of this server, all the features mentioned above are possible. Additionally, it makes presentations and similar activities less time-consuming and a smoother experience.

JavaScript is a dynamic system

There is a long list of powerful systems built around JavaScript with ready-to-use code. All these codes are easy to understand and erase. In addition, depending on the method in question, you will get many other features that will increase your productivity tenfold.

Therefore, if you are a man who knows what he is doing, be sure that there are many tools on the market to get your work done easily and most importantly – quickly.

JavaScript can help perform multiple tasks at once

In technical terms, this is called competition. With JavaScript, you get a program loop module that can execute multiple instructions at once. Imagine that you are browsing a website in your browser and activate a JavaScript program. When triggered, the JavaScript timer stores the message in the message queue. Now if a callback operation is executed that has saved information, it will be executed again in the loop.

So, as you can see, it is possible to handle many tasks in one thread. This helps programmers not have to commit to programming (or working) for different applications.
