Deeply Freeze a Nested Object

To deeply freeze a nested object or array in JavaScript, you need to freeze not only the outer object but also any nested objects or arrays. You can achieve this by creating a recursive function that applies Object.freeze() to all levels of the object.

Here’s an example of how to implement deep freezing:

DeepFreeze Function

Usage Example

How It Works:

• The deepFreeze() function freezes the object itself, and for each property that is an object (or array), it recursively freezes those as well.
• The function ensures that all levels of the object/array hierarchy are made immutable, preventing any modifications.

This method ensures full immutability for complex objects with nested structures.
