Is typescript and javascript same?

In the modern-day world, websites are used rigorously by every business and company to increase the organization’s credibility. But the question that arises in the mind of the early developer is that is typescript and javascript same? JavaScript is a scripting language that aids in building robust and engaging web pages, but Typescript is the superset of JavaScript. 

JavaScript is a client-side scripting language developed by Netscape in 1995. JavaScript is the most sought-after programming language that most websites use to get great, dynamic content. Animations, drop-down menus, and hover interactivity are a few prime features available only with JavaScript. But with growing popularity, TypeScript can be considered a magnified, latest version of JavaScript. 

TypeScript is employed to build JavaScript applications to get executed on both the client and server sides. It is intended to build large applications and websites and trans-compiled to JavaScript. It is an Object-oriented programming language. The code of TypeScript can run on any browser, device, or operating system. TypeScript can let developers use existing JavaScript code, and integrate popular JavaScript libraries, and it can also be called from other JavaScript code. 

Here is the Checklist of five main differences between TypeScript and JavaScript:

1. Definition: TypeScript is the syntactical superset of JavaScript that can overcome the coding difficulty of large, complex projects. It includes all the JavaScript features along with a few additional ones. It was created and maintained by Microsoft. Typescript came into existence due to the drawbacks of JavaScript. Whereas JavaScript is the scripting language that assists in creating engaging web page content. It was first built at Netscape and is maintained by ECMA nowadays. Acceptance and validation of user inputs can only be possible through JavaScript.

2. Ecosystem: TypeScript facilitates both static and dynamic typing of various idiomatic JavaScript traits like union and intersection, whereas JavaScript does not support type static typing. It renders an alternative to finding and forming code without any build setup. Static typing lets developers check type correctness at compile time. TypeScript codes compile before execution, whereas JavaScript codes get interpreted during execution.

3. Prototyping and Learning curve: TypeScript has a prototyping feature, whereas JavaScript doesn’t have this feature. TypeScript has a rigid learning curve therefore, it requires knowledge of scripting. On the other side, JavaScript is simple and easy to learn and is a flexible language for writing web scripts. TypeScript has an interface, but JavaScript does not.

4. Annotation: To get the most out of TypeScript, developers and programmers must constantly elucidate the code, whereas no annotations are needed for JavaScript. TypeScript code is not intelligible by web browsers. That is the reason why code written in TypeScript has to first be translated into JavaScript. Browsers can read and display the JavaScript code.

5. File Extensions, Companies, and Communities: TypeScript have .tsx, and .ts file extensions, whereas JavaScript uses .js file extension. JavaScript codes can be transformed to TypeScript by changing the extension from .js to .ts. TypeScript has been used by companies like Asana, Clever, and Screen Award and on the other hand sites like Airbnb, Instagram, and Codecademy make use of JavaScript. TypeScript has a shorter software developers community whereas JavaScript has a vast community of software developers.
