A call to `throttle(func, ms)` returns `wrapper`.
1. During the first call, the `wrapper` just runs `func` and sets the cooldown state (`isThrottled = true`).
2. In this state all calls memorized in `savedArgs/savedThis`. Please note that both the context and the arguments are equally important and should be memorized. We need them simultaneously to reproduce the call.
3. ...Then after `ms` milliseconds pass, `setTimeout` triggers. The cooldown state is removed (`isThrottled = false`). And if we had ignored calls, then `wrapper` is executed with last memorized arguments and context.

3. After `ms` milliseconds pass, `setTimeout` triggers. The cooldown state is removed (`isThrottled = false`) and, if we had ignored calls, `wrapper` is executed with the last memorized arguments and context.
The 3rd step runs not `func`, but `wrapper`, because we not only need to execute `func`, but once again enter the cooldown state and setup the timeout to reset it.
