konst/index.js

Just like React's `keyMirror` module, but takes an array as input instead.

'use strict';

module.exports = function(constants) {
  var result = {};
  var i = -1;
  var len = constants.length;
  var constant;
  while (++i < len) {
    constant = constants[i];
    result[constant] = constant;
  }
  return result;
};
