TypeScript vs JavaScript

Differences Between TypeScript vs JavaScript

Before we are going to compare TypeScript vs JavaScript programming language we should first know some basic things about TypeScript vs JavaScript languages.

 Typescript: It is an open-source programming language. It is designed by Anders Hejlsberg, designer of C# at Microsoft. It is Licensed under Apache 2. We can call it a superset of javascript. It is design and development especially for large application and trans compile to javascript. It means that Typescript is JavaScript with some extra loaded features.

 Javascript: It was invented by Brendan Eich in 1995 for Netscape Navigator web browser of Netscape. It is implemented in C and its code name was Spider Monkey.

 The project originally called as Mocha then rename to Live Script and finally when Netscape and Sun did license agreement, it was again renamed to JavaScript. It got the ECMA standard in 1997. It is a dynamic programming language. It is used in web development for enhancing HTML pages.

Key Differences Between TypeScript vs JavaScript

After going through section B we already came to know about the difference and similarities of the both JavaScript vs Typescript.

However, the basic key difference between Typescript and JavaScript is summarized below:

• The main advantage of Typescript over JavaScript is Typescript is a superset of JavaScript. So Typescript designed for development of a large program that trans compile to JavaScript.
• JavaScript is used in development for enhancing HTML pages in an interactive and design fashion. It used, particularly in client side. But Typescript may be used to develop a JavaScript application for both client-side and server side. It is designed for development of a large application that trans compile to JavaScript.
• One of the main advantages of JavaScript is that it does not require costly development tools, you can start with a simple text editor such as notepad. Since it is an interpreted language inside a web browser, so you don’t even need to buy a compiler. Whereas its counterpart, Typescript is included as a first-class programming language support expensive IDE visual studio 2013 update 2 and Eclipse via a plug in a contribution by particular technologies.
• We cannot use JavaScript as a full-fledged programming language as it lacks various important features such as client-side javascript does not allow the reading or writing of files whereas Typescript is strongly typed object-oriented compile language. It is both a language and set of tools.
• Typescript supports other JavaScript libraries and Typescript generated JavaScript can reuse all JavaScript frameworks, tools, and libraries.
• The main reason behind the development of typescript by Microsoft is to make it used in the development of large-scale application both at Microsoft and among their external customers.
• JavaScript cannot be used for a network application, because it doesn’t have such support available and also JavaScript does not have any multithreading or multiprocessing capabilities.
• Typescript support definition file which can hold up type information of existing JavaScript libraries, much like C++ header files. Which can describe the structure of existing object files? So this allows other programs to use the values defined in the files.
• Typescript compiler is written in Typescript and it compiles to JavaScript.

Conclusion – TypeScript vs JavaScript

Based on the above discussion between TypeScript vs JavaScript, we can conclude that Typescript vs JavaScript have of its own features and limitation.

JavaScript is a dynamic programming language, light weighted and especially used for enhancing HTML web pages. But it is not a fully fledge programming language. It is an interpreted language inside the context of a web browser.

Typescript is a superset of JavaScript. It means that Typescript is JavaScript plus other features. It compiled to JavaScript which can be used for any JavaScript Code so, using Typescript has more advantages. Its popularity and its adoption are increasing drastically. The project is improving with every release and more exciting features are added with new releases.
