JavaScript Debounce Async Function

In JavaScript, the debounce function is a core tool for optimizing high-frequency and time-consuming operations. Its core logic lies in delaying function execution while canceling repeated delays. This ensures that when a function is triggered multiple times within a short period, it will only execute after waiting for a specified delay following the last trigger. This avoids performance overhead caused by unnecessary invocations. The working principle can be analogized to "an elevator closing its doors": After an elevator opens, it waits for a fixed period (e.g., 2 seconds) by default before closing. If a new passenger enters during this waiting period (corresponding to a new trigger of the function), the original waiting timer is canceled and the countdown restarts. Only when no new triggers occur after the countdown ends will the "door-closing" action (corresponding to the function execution) take place.
