What is Debouncing?
It is a programming technique used to ensure that a function is not called too frequently. It forces the function to wait for a specific period of inactivity before executing.
Working:
• An event (like a keypress) triggers a timer.
• If the same event occurs again before the timer finishes, the old timer is cleared.
• A new timer starts from scratch.
• The actual function only runs once the timer finally hits zero without being interrupted.
Problem Solved:
It prevents performance lag and "server spam" by stopping a function from running hundreds of times per second during rapid actions.
Use Case:
In a search input field, debouncing waits for the user to stop typing for 300ms before making an API call, rather than searching for every single letter.
