Presentation

function memoize(

  resolverOrOptions?:
    | ((...args: Parameters<TFunc>) => string)
    | MemoizeOptions<TFunc>
    | undefined,
): TFunc;

Returns

TFunc -

Name	Type	Description
fn	`TFunc`	Function to memoize
resolverOrOptions	`((...args: Parameters<TFunc>) => string) \| MemoizeOptions<TFunc> \| undefined`	Optional key resolver function or options object

Example usage

const expensive = (a: number, b: number) => a + b;
const memoized = memoize(expensive); // Uses default maxSize of 100

// With custom resolver
const withResolver = memoize(expensive, (a, b) => `${a}-${b}`);

// With custom maxSize
const small = memoize(expensive, { maxSize: 10 });
