A memoization algorithm that only caches the result of the latest set of arguments, where argument equality is determined via a provided equality function. The default areEqual function is a strict equality check on the first four arguments provided.

Quick Start

import memoOne from '@essentials/memoize-one'

const toUpper = memoOne(
  (value) => value.toUpperCase(),
  // are equal?
  (args, prevArgs) => args[0] === prevArgs[0]
)

toUpper('foo')
// FOO (uncached)
toUpper('foo')
// FOO (cached)
toUpper('foobar')
// FOOBAR (uncached)
toUpper('foo')
// FOO (uncached)

API
