memo

Like the memoize function, but simpler and smaller.

The cache key will be generated by joining all the args together and the cache will never expire.

Usage

js

import { memo } from '@studiometa/js-toolkit/utils';

function heavyFunction(a, b) {
  return a.replace(/foo/g, b);
}

const memoHeavyFunction = memo(heavyFunction);

memoHeavyFunction('foo', 'bar'); // bar

Parameters

fn (Function): the function to cache

Return value

This function returns a new function which will cache the first function results.
