Mutable State vs Immutable State
Developers should learn mutable state to build applications that require dynamic updates, such as user interfaces, games, or real-time systems, where data needs to change in response to events or user input meets developers should use immutable state in scenarios requiring predictable state changes, such as in react applications with redux or zustand for ui state management, or in concurrent systems to prevent race conditions. Here's our take.
Mutable State
Developers should learn mutable state to build applications that require dynamic updates, such as user interfaces, games, or real-time systems, where data needs to change in response to events or user input
Mutable State
Nice PickDevelopers should learn mutable state to build applications that require dynamic updates, such as user interfaces, games, or real-time systems, where data needs to change in response to events or user input
Pros
- +It is essential in imperative and object-oriented programming paradigms for managing application state, but must be used carefully to avoid bugs like race conditions or unintended side-effects in concurrent environments
- +Related to: immutable-state, state-management
Cons
- -Specific tradeoffs depend on your use case
Immutable State
Developers should use immutable state in scenarios requiring predictable state changes, such as in React applications with Redux or Zustand for UI state management, or in concurrent systems to prevent race conditions
Pros
- +It is essential for functional programming paradigms, enabling pure functions and referential transparency, and is valuable in distributed systems where data consistency and immutability reduce bugs and improve reliability
- +Related to: functional-programming, redux
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Mutable State if: You want it is essential in imperative and object-oriented programming paradigms for managing application state, but must be used carefully to avoid bugs like race conditions or unintended side-effects in concurrent environments and can live with specific tradeoffs depend on your use case.
Use Immutable State if: You prioritize it is essential for functional programming paradigms, enabling pure functions and referential transparency, and is valuable in distributed systems where data consistency and immutability reduce bugs and improve reliability over what Mutable State offers.
