JavaScript: JavaScript is a programming language which is commonly used in wed development. Its code is only run in web browser.JavaScript is one of the core technologies of world wide web along with HTML and CSS. JavaScript was designed by Brendan Eich and it was first appeared in 4 December 1995.
JScript: JScript is same of JavaScript as JScript was the variant of Microsoft’s JavaScript. JScript was named so for it implementation because Microsoft wanted to avoid trademark issues as trademark of JavaScript is Oracle Corporation.
Differences between JavaScript and JScript:
| The basis of comparison | Javascript | JScript |
| Type | It is a scripting language. | JScript is also a scripting language owned by Microsoft. |
| Verbosity/Simplicity | With JavaScript, one needs to write scripts manually which is time-consuming. | JScript is the same as JavaScript in this context |
| Browser Compatibility | With JavaScript, one needs to handle multiple browser compatibility by writing code. | JScript is only supported by Microsoft’s Internet Explorer. |
| Compilation | We need not compile JavaScript codes. Our browsers run them. | Codes are written in JScript support conditional compilation. With this, we can place codes in block comments and execute them selectively. Starting from Microsoft Internet Explorer 11, conditional compilation is no longer supported |
| Active Content Creation | We can simply write JavaScript codes inside the script tag in HTML. We write JavaScript codes in OBSL syntax (Object Based Script language). | Same goes for JScript. Here also we write the syntax same as JavaScript. |
| Speed | JavaScript is fast. | JScript is also fast. |
| Client Side/Server Side Language | Commonly used on Client Side. | Commonly used on Client Side. |
| Object Access | JavaScript cannot access web browser objects. | JScript can access objects exposed by Internet Explorer. An example of such an object is ActiveX. |
JavaScript is a scripting language developed by Netscape Communications. It was designed for developing client applications initially but later on support for server-side coding was also introduced. There are several frameworks that are built upon JavaScript like JQuery, Angular.js, ReactJS, and Meteor.js to name a few.
Again, in the case of JScript, it can be used and implemented in JavaScript code as well.
JScript is used only in Microsoft Internet Explorer while JavaScript can be executed in any other browsers, for example, Google Chrome, Safari, Firefox, etc.
As per organizational requirements in today’s world, the need for software developers having expertise in JavaScript is considerably more. The demand for JScript is limited to Internet Explorer according to statistics; therefore JScript is not that popular against the huge demand for JavaScript.
