/**
|
|
* Creates an object with the same keys as `object` and values generated by
|
|
* running each own enumerable property of `object` through `iteratee`. The
|
|
* iteratee function is bound to `thisArg` and invoked with three arguments:
|
|
* (value, key, object).
|
|
*
|
|
* If a property name is provided for `iteratee` the created `_.property`
|
|
* style callback returns the property value of the given element.
|
|
*
|
|
* If a value is also provided for `thisArg` the created `_.matchesProperty`
|
|
* style callback returns `true` for elements that have a matching property
|
|
* value, else `false`.
|
|
*
|
|
* If an object is provided for `iteratee` the created `_.matches` style
|
|
* callback returns `true` for elements that have the properties of the given
|
|
* object, else `false`.
|
|
*
|
|
* @static
|
|
* @memberOf _
|
|
* @category Object
|
|
* @param {Object} object The object to iterate over.
|
|
* @param {Function|Object|string} [iteratee=_.identity] The function invoked
|
|
* per iteration.
|
|
* @param {*} [thisArg] The `this` binding of `iteratee`.
|
|
* @returns {Object} Returns the new mapped object.
|
|
* @example
|
|
*
|
|
* _.mapValues({ 'a': 1, 'b': 2 }, function(n) {
|
|
* return n * 3;
|
|
* });
|
|
* // => { 'a': 3, 'b': 6 }
|
|
*
|
|
* var users = {
|
|
* 'fred': { 'user': 'fred', 'age': 40 },
|
|
* 'pebbles': { 'user': 'pebbles', 'age': 1 }
|
|
* };
|
|
*
|
|
* // using the `_.property` callback shorthand
|
|
* _.mapValues(users, 'age');
|
|
* // => { 'fred': 40, 'pebbles': 1 } (iteration order is not guaranteed)
