TypeScript is a superset of JavaScript, meaning that all JavaScript code is valid TypeScript code. The main difference lies in the fact that TypeScript adds static typing and other advanced features such as interfaces, enums, decorators, and more, which are not present in JavaScript.
JavaScript is a dynamic scripting language, while TypeScript is a statically typed language. The static typing in TypeScript allows for type checking at compile-time, which can help catch errors early in the development process. Additionally, TypeScript code is transpiled into JavaScript before it is executed in the browser or server, allowing for broader compatibility.
