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 translates source code into machine code or an intermediate bytecode. Transpilers are particularly useful when developers want to use modern language features that are not yet widely supported by target environments, or when they need to integrate code written in different languages.

The process involves parsing the input code to understand its structure and semantics, then generating equivalent code in the target language. This transformation can range from simple syntactic changes to more complex semantic adaptations. For example, a transpiler might convert modern JavaScript syntax (like ES6 arrow functions) into older, more widely compatible JavaScript versions (like ES5) for older browsers. Another common use case is transpiling languages like TypeScript, which adds static typing and other features to JavaScript, into plain JavaScript that can be executed by any JavaScript engine.

Transpilation plays a significant role in modern software development, enabling the adoption of new technologies and facilitating cross-platform compatibility. It allows developers to leverage the benefits of newer language constructs or features while ensuring their code runs in a variety of environments. The output of a transpiler is typically human-readable source code, which can then be further processed by traditional compilers or interpreters.
