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

 Creates a function that, when executed, will only call the `func` function at most once per every `wait` milliseconds. If the throttled function is invoked more than once during the `wait` timeout, `func` will also be called on the trailing edge of the timeout. Pass an `options` object to indicate that `func` should be invoked on the leading and/or trailing edge of the `wait` timeout. Subsequent calls to the throttled function will return the result of the last `func` call.
