JavaScript is incontestably a language that has grown to be everywhere in the software development world. JavaScript has gained so much popularity that almost every developer wants to be acquainted with it, and almost every website makes use of it.

The number of programming languages being invented keeps increasing, but JavaScript has since 2013 retained the top spot of the most commonly used programming language.

When we even decide to move from the programming language itself to its incidental components, JavaScript-based technologies like AngularJS and Node.JS still tops the list of the most commonly used frameworks, tools, and libraries. The language has reached a level of high significance that it must appear on the top list of every exemplary rating. The Information Technology industry and program developers cannot cease to love JavaScript, which is the reason why it is everywhere on the web, server, mobile, and even on IoT.

The questions that puzzle many concerned people are: Why exactly do these industry giants and considerable number of developers makes use of this language? What exactly is this language capable of doing that makes it so attractive? Why do people keep making JavaScript a topic of discussion? These are reasonable questions that you will get answers to as you keep pursuing this post.

When it comes to benefits, the usefulness of JavaScript to programmers can never be overemphasized. Although there are various places where JavaScript can be applied, but the most common of them all is to use it in a web page. As a matter of fact, some people are aware of the web page as the only place to make use of JavaScript, with is downright false. JavaScript provides a translation to static pages, which allows visitors to interact with a system without having to wait for a new page to load. In other words, JavaScript makes it possible for a visitor to get some tasks done on your website without moving to another page.

Developers understand the essentiality of interaction, and JavaScript provides these forms of interactions, which may include adding of animations to a web page.  A programmer can let a JavaScript pop up a new image, animation, object, or scripts on a web page without having to reload the page. With JavaScript, a visitor of a website do not have fill out a form entirely  and submit it before he/she is informed about his/her error. Quite simply, JavaScript makes web pages dynamic by adding behavior to them.  Apart from making your pages dynamic, JavaScript can also help fix patch holes or browser issues in browser support – for instance, it can help to fix CSS layout issues in some browsers. With its principles of unobtrusive JavaScript, which is sometimes called defensive scripting, JavaScript can test for what is possible in your browser and accordingly react.

Upon its tremendous use, JavaScript is easily implementable. As a matter of fact, all that is required from a JavaScript programmer is to put the JavaScript code in the HTML document and indicate to the browser that it is JavaScript. Learning JavaScript is not rocket science at its core. Getting acquainted to basic language features, async code, Node.js based tooling, and framework structuring is the beginning of it all. Upon being a specialty on its own, most JavaScript developers firstly came through a broader web practice, where they learnt HTML and CSS before the tackle of DOM. Quite simply, web developers who intend to change their static page to a dynamic page usually make use of JavaScript.

The advantages of JavaScript are incompletely stated without making mention of its ability to be used both in frontend and backend. JavaScript can be used in backend with the use Node.js, which is an application runtime environment that permits the writing of server-side applications in JavaScript. Node.js is lightweight, efficient, and highly recommendable. Why exactly is it recommendable? Factually, Node.js makes a team of programmers to be more efficient and cross-functional, for the same software will be used in both frontend and backend.

A tremendously popular program like JavaScript is definitely learnt and demanded all over the world, but evidently, the demand is higher in some countries. Singapore and Indonesia are the two Southeast Asian countries that top the list of countries that are in high demand for JavaScript developers. Singapore’s rank as the leading regional headquarters for multinational corporations, such as Facebook, Apple, and Paypal has caused the demand for JavaScript in Singapore to perpetually escalate.
