 <strong>Throttle</strong> prevents a function from being executed more than once every n milliseconds. Throttling is often used in cases where it&#8217;s disadvantageous to trigger a callback every time an event is triggered (during a continuous action), but you still want to trigger a reaction while the event is occurring. Examples of this would be reacting to the browser window being resized, or animating an element.
 
-<strong>Debounce</strong> prevents a function from being executed until it stops being invoked for n milliseconds. Debouncing is often used to prevent an action from being performed twice, such as double clicking a submit button, or to delay an event from occurring accidentially, such as an even triggered by hover.
