Question 1

How to memoize a function with multiple arguments in memoize?

Accepted Answer

Use the cacheKey option with a serialization function like JSON.stringify on all arguments. For example, set cacheKey: arguments_ => JSON.stringify(arguments_) to cache based on the full argument list, as shown in the README's caching strategy section.

Question 2

Memoize or p-memoize for async functions?

Accepted Answer

Choose p-memoize for Promise-returning functions because it handles Promise-specific behaviors like caching rejections. Memoize works with async functions but lacks these optimizations, as noted in the README's recommendation.

Question 3

How to clear the cache in memoize?

Accepted Answer

Call memoizeClear(fn) on the memoized function to delete all cached entries. This is useful for resetting state or managing memory, and it's documented in the API section with examples.

Question 4

Does memoize support deep equality for objects?

Accepted Answer

No, by default it uses strict equality (===). For deep equality, you must provide a custom cacheKey function, such as using JSON.stringify or libraries like serialize-javascript, as explained in the caching strategy examples.

Question 5

Can I use memoize with React hooks?

Accepted Answer

Yes, but for React-specific memoization, built-in hooks like useMemo are often better integrated. Memoize can optimize expensive calculations in components, but requires manual setup and may not handle React's re-renders as seamlessly.

Question 6

What happens when the cache expires in memoize?

Accepted Answer

When maxAge is set, cache entries automatically expire after the specified milliseconds. Subsequent calls recompute the function and refresh the cache, preventing stale data without extra code.
