/**

|
|
* Iterates over an object's properties and calls the `iteratee` function for each property.
|
||
|
|
*
|
||
|
|
* It only iterates over the object's own properties, not including inherited properties or properties with `Symbol` keys.
|
||
|
|
*
|
||
|
|
* The `iteratee` function can terminate the iteration early by returning `false`.
|
||
|
|
*
|
||
|
|
* @template T - The type of the object.
|
||
|
|
* @param {T | null | undefined} object The object to iterate over.
|
||
|
|
* @param {(value: T[keyof T], key: string, collection: T) => any} [iteratee=identity] The function invoked per iteration. If not provided, the identity function will be used.
|
||
|
|
* @return {T | null | undefined} Returns object.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* function Foo() {
|
||
|
|
* this.a = 1;
|
||
|
|
* this.b = 2;
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* Foo.prototype.c = 3;
|
||
|
|
*
|
||
|
|
* forOwn(new Foo(), function(value, key) {
|
||
|
|
* console.log(key);
|
||
|
|
* });
|
||
|
|
* // => Logs 'a' then 'b' (iteration order is not guaranteed).
