JavaScript vs TypeScript: Which One To Choose

TypeScript derives from JavaScript but allows larger and robust application development.

Are you a frequent JS user? Did you ever consider using TypeScript? This article is dedicated to analyzing both. Their pros and cons, their history, and their differences.

JavaScript is a scripting language that helps developers build interactive webpages. It follows the rules of client-side programming, meaning that the written program runs in the user's web browser without extending to the webserver.

TypeScript is a scripting language based on JavaScript. It’s a modernized version of it and includes type syntax. It is statically compiled and it runs on Node.js.

TypeScript provides static typing, extended classes, and an interface. If you are running a large JavaScript project, you can adopt TypeScript to have a more robust application.

Key Differences

• JavaScript is an independent language. Typescript is a superset of JavaScript.

• TypeScript code needs compilation, JavaScript code doesn’t need compilation.

• TypeScript supports prototyping as a feature, JavaScript doesn’t offer this feature.

• TypeScript uses types and interfaces to describe data uses; JavaScript doesn’t.

• TypeScript is the best option for robust and scalable applications. JavaScript was originally built for small-sized applications.

History of Javascript

Developed by Brendan Eich, JavaScript was developed to work for Netscape navigator. After becoming popular, it was firstly named LiveScript. To finally be named JavaScript. Why was It named JS? Because Netscape supported Java within the browser.

JavaScript was launched in September 1995. It took 10 days to develop. 14 months later, Netscape submitted JavaScript to the European Computer Manufacturers Association (ECMA)

In 2005, Eich and Mozilla officially joined ECMA and they together developed E4X. In January 2009, the CommonJS project was launched to define a common standard library. In June 2011 ECMAScript 5.1 was released. 5 years later, ECMAScript 2016 was released. The last and current released version is the 2017 ECMAScript.

Why choose JavaScript?

• Open source projects

• tools for small scripts

• Supports classes, interfaces & modules

• JavaScript runs in any browser

• You can also use JavaScript for writing large apps

• Adds support for classes, interfaces, and modules

History of Typescript

The typeScript was first made public in 2012. It was developed by Microsoft and it took 2 years to build the first version. The first version was called the 0.9 version and it was released in 2013. The official 1.0 version was released in 2014.

In 2014 a new TypeScript compiler was launched. This new compiler worked more effectively, raising the standard to 5 times faster than the previous version.

There were constant changes made to the development of TypeScript. In July 2015, support for modules was added. In November 2016, an added feature for key and mapped types was added.

Why choose Typescript?

• TypeScript supports JS libraries & API Documentation

• It’s based on Javascript

• TypeScript Code can be converted into JavaScript Code

• Better code structuring

• Object-oriented programming

In conclusion, TypeScript is a derivated language, it is a subset of JavaScript. The typeScript was developed by Microsoft and took 2 years of an entire team working for its 0.9 launches. JavaScript was developed by Brendan Eich and Netscape. In the article, we covered things like why to use each one of them, and its differences. Despite TypeScript derives from JavaScript, it is intended to build larger and more robust scalable applications. JavaScript is used for small size applications. TypeScript needs code compilation, JavaScript doesn’t. JavaScript supports prototyping as a feature, JavaScript doesn’t offer this feature.
