+/**
+* Creates a shallow clone of the given object with customization.
+* This method is like `_.clone` except that it accepts a customizer which
+* is invoked to produce the cloned value. If customizer returns undefined,
+* cloning is handled by the method instead.
+*
+* If no customizer is provided, it behaves like `clone`.
+*
+* @template T - The type of the object.
+* @param value - The value to clone.
+* @param [customizer] - The function to customize cloning.
+* @returns A shallow clone of the given object.
+*
+* @example
+* // Clone a primitive value
+* const num = 29;
+* const clonedNum = cloneWith(num);
+* console.log(clonedNum); // 29
+* console.log(clonedNum === num); // true
+*
+* @example
+* // Clone an array
+* const arr = [1, 2, 3];
+* const clonedArr = cloneWith(arr);
+* console.log(clonedArr); // [1, 2, 3]
+* console.log(clonedArr === arr); // false
+*
+* @example
+* // Clone an object
+* const obj = { a: 1, b: 'es-toolkit', c: [1, 2, 3] };
+* const clonedObj = cloneWith(obj);
+* console.log(clonedObj); // { a: 1, b: 'es-toolkit', c: [1, 2, 3] }
+* console.log(clonedObj === obj); // false
+*
+* @example
+* // Clone an object with a customizer
+* const obj = { a: 1, b: 2 };
+* const clonedObj = cloneWith(obj, (value) => {
+*   if (typeof value === 'number') {
+*     return value * 2; // Double the number
+*   }
+*   // Returning undefined uses the default cloning
+* });
+* console.log(clonedObj); // { a: 2, b: 4 }
