Memoize function that saves Typescript types for arguments and return value

memoize.ts

export const memoize = <ARGS extends unknown[], RETURN>(FUNCTION: (...args: ARGS) => RETURN) => {
    const memory = new Map<string, RETURN>();

    return (...args: ARGS) => memory.get(args.join()) || memory.set(args.join(), FUNCTION(...args)).get(args.join());
};
