JavaScript VS JScript: The Ultimate Comparison

JavaScript VS JScript: The Ultimate Comparison

There are a lot of different programming languages in the world. Some of them appear and win the hearts of programmers, and some of them disappear without success. Today we will look at two languages that have long been the favorites of programmers: JavaScript and JScript.

What is JavaScript?

JavaScript is a full — fledged dynamic programming language that is applied to an HTML document, and can provide dynamic interactivity on websites. It was developed by Brendan Eich, co-founder of the Mozilla project, Mozilla Foundation, and Mozilla Corporation.

JavaScript is incredibly versatile and friendly to beginners. With a lot of experience, you can create games, animated 2D and 3D graphics, full-scale applications with databases, and much more!

JavaScript itself is quite compact, but very flexible. Developers have written a large number of tools on top of the main JavaScript language that unlock a huge number of additional features with very little effort.

What is JScript?

JScript is a scripting programming language that can be used to create (write) scripts that will be interpreted by the Windows Script Host component.

At first glance, JScript is very similar to JavaScript (ECMAScript), and this is natural, since the syntax, some objects, methods, and properties are similar to JavaScript. But this is still not JavaScript, namely JScript. JavaScript (ECMAScript) is focused on browser objects, and JScript is already focused on components of the Windows operating system.

Differences between JavaScript and JScript

Compilation

  • JavaScript: We don’t need to compile JavaScript codes. Our browsers run them themselves.
  • JScript: The codes which are written in JScript support conditional compilation. At the same time, we can place codes in the comments to the block and execute them selectively. Starting with Microsoft Internet Explorer 11, conditional compilation is not supported.

Syntax

  • JavaScript: JavaScript syntax is similar to C++ and Java. If you have experience with C++ or Java, The JavaScript syntax will seem familiar to you. However, the inner workings of JavaScript are closer to a dynamically typed, interpreted language such as Python or Ruby. Here, we write codes inside the script tag in HTML.
  • JScript: In JScript we write the same syntax as JavaScript.

Object Access

  • JavaScript: JavaScript cannot access objects within the web browser.
  • JScript: JScript can access objects provided by Internet Explorer. An example of such an object is ActiveX.

Client / Server language

  • JavaScript: Usually used on the client side.
  • JScript: Usually used on the client side.

Browser compatibility

  • JavaScript: When using JavaScript, you must maintain compatibility with multiple browsers by writing code.
  • JScript: JScript is only supported by Microsoft Internet Explorer.
