Usage Scenarios

These two functions can be taken into account as long as they are involved in a continuous event or frequency control-related application, such as:

• Game shooting, KeyDown events
• Text input, AutoComplete, KeyUp events
• Mouse movement, MouseMove events
• DOM element dynamic positioning, resize and scroll events for window objects

There's a metaphor in the article.

• throttleStrategy of the elevator. Ensure that if the elevator first person comes in, 15 seconds after delivery on time, do not wait. If there is no one, then standby.
• debounceStrategy of the elevator. If someone comes in the elevator, wait 15 seconds. If another person comes in, 15 seconds waits for a re-timer until 15 seconds expires and the shipment begins.

The commentary is also wonderful:

Throttle: Trigger-last action execution time greater than limit time, execute action, record execution time
Debounce: Trigger-record trigger time-last action trigger time greater than limit time-perform action

-----------

You can see it.

throttle: Timed fixed point

Debounce: for deferred processing
