Implementing Your Own debounce()

Debounce is a common technique used in web development to improve performance by controlling the rate at which a particular function is invoked.

It is particularly useful in scenarios where user input events, such as keystrokes or mouse movements, trigger function calls that can be resource-intensive.

Understanding Debounce

Imagine a scenario where a user is typing in a search input field, and with each keystroke, an API call is made to fetch search results. Without debouncing, this could lead to multiple API calls for each keypress, potentially causing performance issues.

Debouncing solves this problem by introducing a delay between the user's input and the actual invocation of the associated function. If another input occurs within this delay, the timer resets. This ensures that the function is only executed after the user has finished inputting.
