es6bindall/index.js

Simple function to bind multiple methods to an ES6 class's 'this' object. Intended as an equivalent to Backbone's bindAll() method.

(function (global, factory) {
  if (typeof define === "function" && define.amd) {
    define(["module", "exports"], factory);
  } else if (typeof exports !== "undefined") {
    factory(module, exports);
  } else {
    var mod = {
      exports: {}
    };
    factory(mod, mod.exports);
    global.es6bindall = mod.exports;
  }
})(this, function (module, exports) {
  "use strict";

  Object.defineProperty(exports, "__esModule", {
    value: true
  });
