Throttling vs Debouncing

Throttling is a straightforward reduction of the trigger rate. It will cause the event listener to ignore some portion of the events while still firing the listeners at a constant (but reduced) rate.

Unlike throttling, debouncing is a technique of keeping the trigger rate at exactly 0 until a period of calm and then triggering the listener exactly once.

In other words

With Throttling the original function is called at most once per specified period.
