/**
|
|
* Iterates over own and inherited enumerable properties of an object invoking
|
|
* `iteratee` for each property. The iteratee is invoked with three arguments:
|
|
* (value, key, object). Iteratee functions may exit iteration early by explicitly
|
|
* returning `false`.
|
|
*
|
|
* @static
|
|
* @memberOf _
|
|
* @category Object
|
|
* @param {Object} object The object to iterate over.
|
|
* @param {Function} [iteratee=_.identity] The function invoked per iteration.
|
|
* @returns {Object} Returns `object`.
|
|
* @example
|
|
*
|
|
* function Foo() {
|
|
* this.a = 1;
|
|
* this.b = 2;
|
|
* }
|
|
*
|
|
* Foo.prototype.c = 3;
|
|
*
|
|
* _.forIn(new Foo, function(value, key) {
|
|
* console.log(key);
|
|
* });
|
|
* // => logs 'a', 'b', then 'c' (iteration order is not guaranteed)
