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.
