jsdc

jsdc is a JavaScript transpiler that converts ES6/ES2015 code to ES5 for backward compatibility. Current stable version is 0.6.13, last released in 2017. It focuses on safe transformations preserving line numbers for debugging, supports CommonJS/AMD/CMD, and includes features like let/const, arrow functions, classes, generators, destructuring, template literals, and modules. Unlike Babel or Traceur, jsdc is lightweight, has no runtime dependencies, and aims for simplicity. The project appears to be in maintenance mode with no recent updates.
