The Ultimate Comparison between JavaScript and JScript

JavaScript VS JScript: The Ultimate Comparison

There are numerous programming languages available in the world. Some of them arise and win the hearts of programmers, while others vanish without a trace. Today, we’ll look at two programming languages that have a long favorite: JavaScript and JScript.

What is JavaScript?

JavaScript is a whole-fledged dynamic programming language that may create dynamic interactivity on websites when applied to an HTML document. Brendan Eich, the co-founder of the Mozilla project, Mozilla Foundation, and Mozilla Corporation, made it.

JavaScript is highly versatile and user-friendly. You can design games, animated 2D and 3D images, full-scale apps with databases, and much more with a lot of experience!

JavaScript is a small but powerful programming language. On top of the fundamental JavaScript language, developers have created many tools that unlock a plethora of additional functionality with minimal effort.

What is JScript?

JScript is a scripting computer language used to produce (write) scripts processed by the Windows Script Host component.

JScript appears to be quite similar to JavaScript (ECMAScript) at first glance, which is unsurprising given that the syntax, some objects, methods, and properties are comparable to JavaScript. However, this is not JavaScript, but rather JScript. JavaScript (ECMAScript) is focused on browser objects, whereas JScript is already focused on Windows operating system components.

Differences between JavaScript and JScript


  • 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.


  • 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.
