Non-Deterministic Functions vs Pure Functions
Developers should learn about non-deterministic functions when building applications that rely on randomness, such as games, simulations, or cryptographic systems, or when dealing with real-time data like timestamps or user inputs 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.
Non-Deterministic Functions
Developers should learn about non-deterministic functions when building applications that rely on randomness, such as games, simulations, or cryptographic systems, or when dealing with real-time data like timestamps or user inputs
Non-Deterministic Functions
Nice PickDevelopers should learn about non-deterministic functions when building applications that rely on randomness, such as games, simulations, or cryptographic systems, or when dealing with real-time data like timestamps or user inputs
Pros
- +Understanding them is essential for debugging and testing, as their unpredictable nature can lead to challenges in reproducibility and consistency, requiring strategies like mocking or seeding
- +Related to: deterministic-functions, random-number-generation
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 Non-Deterministic Functions if: You want understanding them is essential for debugging and testing, as their unpredictable nature can lead to challenges in reproducibility and consistency, requiring strategies like mocking or seeding 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 Non-Deterministic Functions offers.
Developers should learn about non-deterministic functions when building applications that rely on randomness, such as games, simulations, or cryptographic systems, or when dealing with real-time data like timestamps or user inputs
