|
* Creates a deep clone of the given object using a customizer function.
|
||
|
|
*
|
||
|
|
* @template T - The type of the object.
|
||
|
|
* @param {T} obj - The object to clone.
|
||
|
|
* @param {Function} [cloneValue] - A function to customize the cloning process.
|
||
|
|
* @returns {T} - A deep clone of the given object.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* // Clone a primitive value
|
||
|
|
* const num = 29;
|
||
|
|
* const clonedNum = cloneDeepWith(num);

|
|
* console.log(clonedNum); // 29
|
||
|
|
* console.log(clonedNum === num); // true
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* // Clone an object with a customizer
|
||
|
|
* const obj = { a: 1, b: 2 };
|
||
|
|
* const clonedObj = cloneDeepWith(obj, (value) => {

* console.log(clonedObj); // { a: 2, b: 4 }
|
||
|
|
* console.log(clonedObj === obj); // false
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* // Clone an array with a customizer
|
||
|
|
* const arr = [1, 2, 3];
|
||
|
|
* const clonedArr = cloneDeepWith(arr, (value) => {
|
||

* return value + 1; // Increment each value

* });
|
||
|
|
* console.log(clonedArr); // [2, 3, 4]
