TypeScript is composed of several key components that work together to enhance JavaScript with type safety and other features. Here are the main components of TypeScript:
Language: This includes the syntax, keywords, and type annotations that define the structure of TypeScript code. The language component is fundamental as it specifies the rules and capabilities of TypeScript, such as defining interfaces, types, classes, and other constructs[1][2].
TypeScript Compiler (TSC): The TypeScript compiler is a crucial component that transforms TypeScript code into plain JavaScript. This conversion is necessary because browsers and most environments do not natively execute TypeScript. The compiler also handles parsing and type-checking, ensuring that the TypeScript code adheres to the defined types before it is compiled into JavaScript. The TypeScript compiler supports various JavaScript modules like ES6, SystemJS, and AMD, and can be installed locally or globally[1][2].
TypeScript Language Service: This component provides additional functionalit...
