Transpiler

Definitions

1. A source-to-source compiler that translates code from one programming language (or language version) to another at a similar level of abstraction. Babel transpiling modern JavaScript to older JavaScript is the canonical example.

   In plain English: A tool that converts code from one programming language to another — like translating French to Spanish rather than French to machine beeps.
