How to clone Object in javascript

In JavaScript, object cloning refers to creating a copy of an existing object. Shallow cloning involves duplicating the object's structure and references to its properties, typically achieved through methods like the spread operator (...) or Object.assign(). These methods create a new object with the same properties and values as the original. However, they only create a shallow copy, meaning if the object contains nested objects, they're still referenced and not cloned recursively.

For deep cloning, which involves creating copies of nested objects as well, it's more complex. Libraries like Lodash provide functions such as _.cloneDeep() to accomplish this, ensuring complete independence of the cloned object from the original. Deep cloning is essential when dealing with complex data structures to prevent unintended changes across objects.
