import debounce
Debounce is a utility function that helps limit the number of times a function is called in a certain time frame. It is commonly used in scenarios where a function is triggered frequently, such as handling user input events like key presses or mouse movements.
The debounce function works by delaying the execution of a function until a certain amount of time has passed since the last call. If the function is called again within that time frame, the timer is reset and the function execution is delayed again. This helps avoid unnecessary or excessive function calls, especially in cases where the function's execution is resource-intensive or time-consuming.
Here is an example of how to use the debounce function in JavaScript:
```javascript
function handleInput() {
// Function logic goes here
}
const debouncedHandleInput = debounce(handleInput, 200); // Debounce for 200ms
// Attach the debounced function to the input event
document.getElementById('inputElement').addEventListener('input', debouncedHandleInput);
```
In this example, the `handleInput` function will only be executed once every 200 milliseconds, regardless of how frequently the `input` event is triggered. This helps optimize performance and prevents unnecessary function calls.
Debounce is a commonly used utility function in web development and can be found in various JavaScript libraries and frameworks.
