JScript and JavaScript are different names for the same language. However, there are certain differences between these two languages. This article gives you the points which will make you understand the difference between JScript and JavaScript.
What exactly is JavaScript?
Well, JavaScript is a client-side scripting language used for developing interactive and dynamic web pages. It is an object-based, high-level language that was developed by Brendan Eich at Netscape in 1995. Along with HTML and CSS, JavaScript is considered as one of the key technologies used for developing web pages. The first browser that supported JavaScript was Netscape Navigator 2.0. Presently, it is supported by all the major web browsers.
Today, JavaScript is being used for server-side coding as well. Several frameworks are built upon JavaScript such as JQuery, Node.js, Angular, etc.
What is JScript?
JScript is also a client-side scripting language like JavaScript. They are used for developing interactive and dynamic content for the web pages. It is a product of Microsoft that was first released in 1996. The first browser that supported JScript was Internet Explorer 3.0. The recent version of JScript is JScript 9.0 included in Internet Explorer 9.
Thus, both languages are similar in a way that they are client-side scripting languages. Both are used for making the boring and dull web pages as interactive and dynamic. Both are based on ECMAScript (European Computer Manufacturer’s Association) standard.
The Difference
The main differences to be noted in their functionality are as follows:
- Owner: JScript is owned by Microsoft. JavaScript is owned by Internet Explorer.
- Browser Compatibility: Only Microsoft Internet Explorer supports JScript. JavaScript is supported by all the major web browsers like Chrome, Firefox, Safari, etc.
- Active Content Support: JScript supports active content creation like internet polls, ActiveX applications, weather maps, etc. JavaScript does not support it.
- Accessing Browser Objects: JScript can access browser objects exposed by Internet Explorer such as ActiveX while JavaScript cannot access browser objects.
- Conditional Compilation: JScript supports conditional compilation. This allows the programmer to execute the codes written within block comments selectively. This feature is no longer supported starting from Internet Explorer 11.0.
Conclusion
Both languages are similar when used as scripting languages. They differ in the means they provide to perform a particular task.
JavaScript can be used in any of the web browsers and JScript can be used with Internet Explorer. The only advantage of JScript is its ability to access browser objects. This is not supported in JavaScript.
