 We debounced with a window of 150ms. The bursts of emissions in our observable were faster than that (100ms), so only the last value in each burst passed through. During the slower part of our observable, all the values were accepted, because the 150ms window expired before the next value arrived.
 
+There is a `throttleWithTimeout` operator which has the same behaviour as the `debounce` operator that we just saw.  One is practically an alias of the other, even though neither is officially declared as such in the documentation.

 You can also debounce based on a per item basis. In this case, you provide a function that calculates for each item how long the window should be after it. You signal that the window is over though an observable. When the observable terminates, the window expires.
