  • extend.js

  • ¶

    Taken from Underscore. Given a list of arguments, extend a root object with those values.

    For example:

     extend({ red: 'red' }, { blue: 'blue' });

    var _        = require('./collection');
var isObject = require('./isObject');

module.exports = function(root) {
  • ¶

    Remove all keys that are not objects, for safety

      var valid = _.filter(arguments, isObject);
  • ¶

    For each valid argument

      valid.forEach(function(source) {
  • ¶

    Take each member key of the source object

        Object.keys(source).forEach(function(key) {
  • ¶

    And assign it to the root object

          root[key] = source[key];
    });

  });

  return root;
};
