* Iterates over an object in reverse order and invokes the `iteratee` function for each property.
|
|
*
|
|
* Iterates over string keyed properties including inherited properties in reverse order.
|
|
*
|
|
* The iteration is terminated early if the `iteratee` function returns `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, obj: T) => any} iteratee - The function invoked per iteration
|
|
* @returns {T | null | undefined} Returns the object
|
|
*
|
|
* @example
|
|
* // Iterate over all properties including inherited ones
|
|
* const obj = { a: 1, b: 2 };
|
|
* forInRight(obj, (value, key) => {
|
|
* console.log(key, value);
|
|
* });
|
|
* // Output: 'b' 2, 'a' 1
|
|
*
|
|
* // Early termination
|
|
* forInRight(obj, (value, key) => {
|
|
* console.log(key, value);
|
|
* return key !== 'a'; // stop after 'a'
|
|
* });
|
|
* // Output: 'b' 2
