Mutable State vs Pure Functions
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 learn and use pure functions to write more maintainable, testable, and bug-resistant code, especially in functional programming paradigms like haskell or when building applications with frameworks like react that emphasize immutability. 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
Pure Functions
Developers should learn and use pure functions to write more maintainable, testable, and bug-resistant code, especially in functional programming paradigms like Haskell or when building applications with frameworks like React that emphasize immutability
Pros
- +They are crucial for concurrency and parallelism, as they avoid shared mutable state, and are ideal for data transformation tasks, such as in data pipelines or mathematical computations, where predictability is key
- +Related to: functional-programming, immutability
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 Pure Functions if: You prioritize they are crucial for concurrency and parallelism, as they avoid shared mutable state, and are ideal for data transformation tasks, such as in data pipelines or mathematical computations, where predictability is key over what Mutable State offers.
