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.
