/**
|
||
|
|
* A relative of [`map`]{@link module:Collections.map}, designed for use with objects.
|
||
|
|
*
|
||
|
|
* Produces a new Object by mapping each value of `obj` through the `iteratee`
|
||
|
|
* function. The `iteratee` is called each `value` and `key` from `obj` and a
|
||
|
|
* callback for when it has finished processing. Each of these callbacks takes
|
||
|
|
* two arguments: an `error`, and the transformed item from `obj`. If `iteratee`
|
||
|
|
* passes an error to its callback, the main `callback` (for the `mapValues`
|
||
|
|
* function) is immediately called with the error.
|
||
|
|
*
|
||
|
|
* Note, the order of the keys in the result is not guaranteed. The keys will
|
||
|
|
* be roughly in the order they complete, (but this is very engine-specific)

|
* @category Collection
|
||
|
|
* @param {Object} obj - A collection to iterate over.
|
||
|
|
* @param {Function} iteratee - A function to apply to each value and key in
|
||
|
|
* `coll`. The iteratee is passed a `callback(err, transformed)` which must be
|
||
|
|
* called once it has completed with an error (which can be `null`) and a
|
||
|
|
* transformed value. Invoked with (value, key, callback).
|
||
|
|
* @param {Function} [callback] - A callback which is called when all `iteratee`
|
||
|
|
* functions have finished, or an error occurs. Results is an array of the
|
||
|
|
* transformed items from the `obj`. Invoked with (err, result).
|
||
|
|
* @example
|
||
|
|
*
|
||
|
|
* async.mapValues({
|
||
|
|
* f1: 'file1',
|
||
|
|
* f2: 'file2',
|
||
|
|
* f3: 'file3'
|
||
|
|
* }, function (file, key, callback) {
|
||
|
|
* fs.stat(file, callback);
|
||
|
|
* }, function(err, result) {
|
||
|
|
* // results is now a map of stats for each file, e.g.
|
||
|
|
* // {
|
||
|
|
* // f1: [stats for file1],
|
||
|
|
* // f2: [stats for file2],
|
||
|
|
* // f3: [stats for file3]
|
||
|
