  • Integration with other state management libraries like Redux and MobX
  • Lightweight and efficient, with a small code size and fast performance
  • Easy to learn and use, with a simple API and clear documentation

#Immer Use-Cases

Some of the Immer use-cases are:

  • Managing state in large-scale applications, where complex data structures are common
  • Simplifying updates to nested objects and arrays, reducing the risk of bugs and errors
  • Improving performance by reducing the number of object and array copies needed for immutable updates
  • Simplifying integration with other state management libraries, reducing the need for complex data transformation logic
  • Writing more concise and expressive code, by reducing the need for manual object and array copying
  • Improving the reliability and stability of applications, by reducing the risk of unexpected state changes.
