What is the primary role of JavaScript?

Students who learn programming are no strangers to JavaScript, which is a very important part of front-end technology. F or example, page effect switching, animation effects, page games, and so on. I n fact, we can already build pages of all styles with HTML and CSS technology, but you need JavaScript technology to make the page really dynamic. Here's a little editor to give you a closer look at what JavaScript's main role is.

Encyclopedia defines JavaScript as a translated scripting language, a dynamic type, a weak type, a prototype-based language, and a built-in support type. Although JavaScript uses the name Java, it doesn't really have anything to do with Java.

In addition, JavaScript's use is no longer limited to browsers, and the advent of Node .js has enabled developers to write JavaScript code on the server side, making JavaScript more widely available.

There are already a number of large Internet companies that have separate JavaScript technology development positions. E specially in the context of the continuous development of large front-end technology, front-end development engineers from the beginning of simple page development to the front-end fusion development, cross-platform development and other fields. A s a very promising technology direction, JavaScript is bound to occupy a more important position in the future Internet space. Learning front-end technology alone can not adapt to the real needs of enterprises today.
