In shallow copy, an object is copied and the main object reference changes, and the child or child of child object references do not change. The spread operator does a shallow copy

Helps in copying deep by creating new references for all the child objects. Libraries like lodash help to easily perform a deep copy.
But deep copy affects the performance.
