transpilaator

A transpiler, also known as a source-to-source compiler, is a program that takes source code written in one programming language and converts it into source code in another programming language. This is distinct from a traditional compiler, which typically translates source code into machine code or an intermediate bytecode that can be executed by a virtual machine. Transpilers operate at a higher level of abstraction, transforming code that is often human-readable into equivalent code in a different, but also human-readable, language.

The primary motivation for using transpilers is to leverage features or environments associated with a different language. For example, transpilers are commonly used to translate modern JavaScript code, which uses features like classes and arrow functions, into older versions of JavaScript that are compatible with a wider range of web browsers. Another common use case involves translating code written in a higher-level language, such as TypeScript or CoffeeScript, into standard JavaScript for execution in web environments.

Transpilation can also facilitate code migration between languages or allow developers to use a preferred language while targeting a platform that only supports another. For instance, some tools transpiles code written in languages like Python or Dart into JavaScript, enabling their execution in web browsers. This process can be particularly useful for web development, allowing for the use of more expressive or feature-rich languages that ultimately compile down to the ubiquitous JavaScript. The output of a transpiler is generally intended to be as functionally equivalent as possible to the original source code.
