A composition of lodash utilities that produces a function which changes the way any function passed to it receives parameters.

inject.js

import _ from 'lodash';

// return a function where the keys in the passed object will be
// applied as arguments.

/*
var foo = function (a, b, c, d) {
  // does stuff
};

foo(1, 0, 'fi', 'fo');

var bar = inject(foo, ['a', 'b', 'goo', 'boo']);

bar({
  a: 1,
  b: 0,
  goo: 'fi',
  boo: 'fo'
});

  return function (obj) {
    var params = _.at(obj, keys);
    var spreaded = _.spread(fn);
