Question 1

How to handle asynchronous errors with Pratica?

Accepted Answer

Pratica does not have built-in async monads, so you need to manually integrate with promises. For example, use encaseRes to wrap async functions that may throw errors, but for more complex async flows, consider combining it with other libraries or custom promise handling.

Question 2

Pratica vs Folktale: which is better for functional programming?

Accepted Answer

Pratica is lighter and more pragmatic, focusing on Maybe and Result for safe data handling, while Folktale is a comprehensive FP library with more algebraic data types and features. Choose Pratica for simplicity and quick adoption, but Folktale for advanced FP needs.

Question 3

Can I use Pratica with TypeScript?

Accepted Answer

Yes, Pratica can be used with TypeScript as it's a JavaScript library, but the README doesn't mention built-in type definitions. You may need to add custom types or rely on community contributions for full TypeScript support.

Question 4

How to convert existing if-else chains to Pratica Result monad?

Accepted Answer

Wrap conditional logic in functions that return Ok or Err based on conditions, then chain them using .chain() for sequential checks. This replaces nested if-else statements with a functional pipeline that short-circuits on errors.

Question 5

Is Pratica suitable for front-end frameworks like React?

Accepted Answer

Yes, Pratica can be used in React for state management or error handling by wrapping components or hooks with its monads. However, it's not specifically designed for React, so integration might require additional setup for context or effects.

Question 6

What are the performance implications of using Pratica?

Accepted Answer

Pratica is lightweight with a small bundle size, so runtime overhead is minimal. The monadic approach involves some abstraction cost, but the safety benefits in preventing null errors often outweigh this in complex data handling scenarios.
