Typescript vs Javascript

What's the difference?

What is JavaScript?

What is TypeScript?

Comparison based on Typing

Comparison based on Ecosystem

Comparison based on Compilation

TypeScript must be compiled, whereas JavaScript does not.

Comparison based on Annotations

Annotations are not required in JavaScript, while TypeScript requires annotations to fully utilize JavaScript features.

Comparison based on Error Detection

Since JavaScript is an interpreted language, errors are only detected at run time, whereas in TypeScript, errors are detected during early development stage.

Comparison based on Execution

JavaScript runs directly on the browser and is cross-platform, cross-browser compatible, whereas the TypeScript script does not run directly on the browser.
