How does Immer produce a new state without deep cloning all objects in the state tree?

  • It creates a completely new state tree from scratch.
  • It relies on JavaScript's native deep cloning functions.
  • It uses a third-party library for cloning.
  • It utilizes structural sharing to create a new state.
Immer employs structural sharing, also known as "copy-on-write," to generate a new state without deep cloning all objects. When changes are made, only the affected objects are cloned, reducing memory and CPU usage. This technique is crucial for efficient state management in applications, particularly in React and Redux.
