72/**
73 * Like [`each`]{@link module:Collections.each}, except that it passes the key (or index) as the second argument
74 * to the iteratee.
75 *
76 * @name eachOf
77 * @static
78 * @memberOf module:Collections
79 * @method
80 * @alias forEachOf
81 * @category Collection
82 * @see [async.each]{@link module:Collections.each}
83 * @param {Array|Iterable|Object} coll - A collection to iterate over.
84 * @param {AsyncFunction} iteratee - A function to apply to each
85 * item in `coll`.
86 * The `key` is the item's key, or index in the case of an array.
87 * Invoked with (item, key, callback).
88 * @param {Function} [callback] - A callback which is called when all
89 * `iteratee` functions have finished, or an error occurs. Invoked with (err).
90 * @example
91 *
92 * var obj = {dev: "/dev.json", test: "/test.json", prod: "/prod.json"};
93 * var configs = {};
94 *
95 * async.forEachOf(obj, function (value, key, callback) {
96 * fs.readFile(__dirname + value, "utf8", function (err, data) {
97 * if (err) return callback(err);
98 * try {
99 * configs[key] = JSON.parse(data);
100 * } catch (e) {
101 * return callback(e);
102 * }
103 * callback();
104 * });
105 * }, function (err) {
106 * if (err) console.error(err.message);
107 * // configs is now a map of JSON data
108 * doSomethingWith(configs);
109 * });
