Primarily, when we think about developing a website, application, or software the foremost concerning question is about the platforms, technology, language, and design. 

Because these factors affect the performance, security, UX/UI, and endurance of the application and software.

Specifically, selecting a scripting language out of JavaScript (JS) and TypeScript (TS) could put you in a dilemma because the difference between JavaScript and TypeScript is compact.

## 1) What is JavaScript?
JavaScript is a prototype-based scripting language widely used for interactive web developments. Besides making web development interactive JavaScript is used for handling the mouse, controlling keyboard events, validating forms, and other website operations.

Initially, JavaScript was introduced as a client-side programming language that works on the user’s browser but later on, developers realized that it could also be used as a server-side programming language too. The difference between TypeScript and JavaScript appears here on which side they are serving- client or server.

JavaScript is ideal for frontend as well as backend frameworks which is compatible with other technologies like REST, APIs, XML, and others.

## 2) What is TypeScript?
TypeScript is a strongly typed and compiled programming language used for scripting heavy and complex web development projects. TypeScript is considered both a language and a set of tools.

Basically, TypeScript is a super-set of JavaScript language because every JavaScript code is valid in TypeScript.

TypeScript is an open-source and object-oriented programming language that has added features, tools, and interfaces.

As we are discussing JavaScript vs TypeScript, here is the table that showcases the difference between TypeScript and JavaScript’s features, tools, and functionality.

## JavaScript vs TypeScript: Which is Best Suitable?

Don’t get confused between JavaScript and TypeScript. TypeScript is the super-set language of JavaScript. The code written in JavaScript can be changed to TypeScript by changing its extension.

- TypeScript is suitable if many developers are working on a single project
- JavaScript is a smart choice for small projects with fewer codes
- If the project is complex and has large codes it is advisable to go with TypeScript
- Runtime overhead can be skipped with TypeScript by undergoing compile-time validation
- If developers are using test-driven development then JavaScript is best suitable
- To leverage the benefits of frameworks like EmberJS, it is good to go with JavaScript
- With TypeScript you can avail the help of IntelliSense if you are not familiar with APIs

## JavaScript vs TypeScript: Which is Best Suitable?

JavaScript vs TypeScript: What Differs JavaScript and TypeScript?
JavaScript is a programming language developed intentionally to create interactive web pages while TypeScript is an object-oriented programming language to create large-scale web apps.

Though there are many similarities between JavaScript and TypeScript here is the list of features that differs JavaScript from TypeScript.
