 Creates a function that memoizes the result of `func`. If `resolver` is provided it will be used to determine the cache key for storing the result based on the arguments provided to the memoized function. By default, the first argument provided to the memoized function is used as the cache key. The `func` is executed with the `this` binding of the memoized function. The result cache is exposed as the `cache` property on the memoized function.
