What is one way to deep clone an object in JavaScript?

Deep cloning an object means creating a new object that is a copy of the original, including all nested objects, rather than just copying the reference to the original object. The method of using JSON.parse(JSON.stringify(object)) effectively achieves this by serializing the entire object into a JSON string and then parsing that string back into a new object.

This approach works well because it creates a completely separate instance of the object, including all of its nested properties. However, it's essential to note that this method only works with data types that are compatible with JSON. For example, functions, undefined, and symbols are not preserved when you serialize and deserialize with JSON, which can be a limitation in certain contexts.

The other methods mentioned do not provide a true deep clone:

• Object.assign() is useful for shallow cloning (copying properties at one level), but it won't copy nested objects properly, leading to shared references between the cloned object and the original.

• Object.create() is designed to create a new object with a specified prototype, but it does not copy properties from an existing object into the new one.

• A for...in loop can iterate over properties of an object, but using it to manually copy properties would result
