    Babel Closure Elimination

    This is a Babel plugin that eliminates unnecessary closures from your JavaScript in the name of performance.

    Build Status

    Note: Now requires Babel 6.

    What?

    Turns code like this:

    function demo (input) {
      return input.map(item => item + 1).map(item => item + 2);
    }

    Into code like this:

    function _ref(item) {
      return item + 1;
    }
     
    function _ref2(item) {
      return item + 2;
    }
     
    function demo(input) {
      return input.map(_ref).map(_ref2);
    }
     

    Why?

    Because it's faster and more memory efficient in most JavaScript engines, and means you can safely use arrow functions without a performance penalty in most cases.
