JavaScript and TypeScript are not the same, although they are related. Here is the detailed explanation:
JavaScript is a high-level programming language that is widely used for creating interactive and dynamic web pages, as well as server-side applications. JavaScript is a dynamically typed language, which means that variables are not assigned a specific data type, and supports features such as closures, functions as first-class objects, and prototypal inheritance.
TypeScript, on the other hand, is a superset of JavaScript that adds optional static typing to the language. TypeScript also supports many of the features of JavaScript, such as closures, functions as first-class objects, and prototypal inheritance, but also includes additional features such as interfaces and classes.
TypeScript is designed to make it easier to write and maintain large-scale JavaScript applications by providing better code organization, enhanced type checking, and improved error detection. TypeScript code is compiled into JavaScript code, which can then be executed by a web browser or server-side engine.
Overall, while JavaScript and TypeScript share many similarities, they are distinct programming languages with different features and use cases. While JavaScript is a more versatile language that can be used for a wide range of applications, TypeScript is specifically designed for building large-scale applications with enhanced type checking and error detection.
