Deep Clone Object

JavaScript

medium

25 mins

Create a function that performs a deep clone of a given JavaScript object. The function should handle nested objects, arrays, and primitive data types without retaining any references to the original object.

Example Inputs & Outputs

const original = { a: 1, b: { c: 2 }, d: [3, 4] };
const cloned = deepClone(original);

console.log(cloned); // { a: 1, b: { c: 2 }, d: [3, 4] }
console.log(cloned !== original); // true
console.log(cloned.b !== original.b); // true
console.log(cloned.d !== original.d); // true

Constraints & Edge Cases

The function should handle objects and arrays of arbitrary depth.
It should not modify the original object.
The function should correctly clone primitive values (number, string, boolean, null, undefined, symbol).
Functions and special objects (like Date, RegExp) are not required to be cloned accurately.
