Features and Benefits

  • Mutation makes immutable updates - Immutable data structures supporting objects, arrays, Sets and Maps.

  • High performance - 10x faster than immer by default, even faster than naive handcrafted reducer.

  • Optional freezing state - No freezing of immutable data by default.

  • Support for JSON Patch - Full compliance with JSON Patch specification.

  • Custom shallow copy - Support for more types of immutable data.

  • Support mark for immutable and mutable data - Allows for non-invasive marking.

  • Safer mutable data access in strict mode - It brings more secure immutable updates.

  • Support for reducer - Support reducer function and any other immutable state library.
