Programming Language

Uses of Javascript Outside Of The Browser

JavaScript is a high-level, untyped, interpreted and dynamic programming language and has also been standardized in the specification of the ECMAScript language. Alongside CSS and HTML, it is one of the three significant technologies of WWW (World Wide Web) content production. Most of the websites use it and it is also supported without plug-ins by all the latest web browsers.

With first-class functions, JavaScript is prototype-based and this makes it a language that is multi-paradigm, supporting functional, imperative and object-oriented programming styles.

It has an API for working with regular expressions, arrays, text and  dates, but does not involve any I/O, for example, graphics, networking or storage facilities, relying for these upon the host atmosphere in which it is embedded.

In spite some naming, standard library and syntactic similarities, Java and JavaScript otherwise have very different semantics and are unrelated. Actually, the syntax of JavaScript is derived from C, whereas the design and semantics are influenced by the Scheme and Self programming languages.

Javascript on the Server Side – Node.js

You can also run Javascript with the help of the server. For example, Node.js indicates that how Javascript can be run on the server side and not the client side.

Basically, the Node.js is a combination of a library and a runtime environment that uses server side Javascript for building web based applications. The key to consider here is that it is server side Javascript. This shows that Javascript is not executed by the browser, but by the server. Beside this, Node.js also uses the V8 virtual machine, which is a Javascript virtual machine generally used in the web browser of Google Chrome.

JavaScript is also employed in atmospheres that are not web-based, for example, desktop widgets, PDF documents and site-specific browsers. You can even use Javascript for customizing PDF files and even for developing Adobe Acrobat applications.

Faster and Newer JavaScript VMs (virtual machines) and platforms built upon them have also strengthened the acceptance of JavaScript for server-side web applications. However, JavaScript has been implemented traditionally as an interpreted language on the client side, but newer browsers perform just-in-time compilation.
