This is a collection of sweet.js macros that implement syntactic ES6 features that can be easily compiled out to ES5 JavaScript, which can be used today everywhere.

Warning: This is still in development and most of these features are not completely compliant with ES6 yet. I wouldn't recommend using it for production code yet.

Currently implemented:

• destructuring (including elision and rest)
• classes
• fat arrow functions

TODO:

• rest and default arguments
• spread operator for applying arguments
• possibly limited for of support
• possibly limited module support

$ npm install sweet.js es6-macros

Write your improved ES6 JavaScript, and compile it:

$ sjs -m es6-macros file.js

If you pass -c to sjs along with -o output.js, it will generate a sourcemap so you get good debugging too!

To run the tests:

npm install
make
