Debounce

?? Understanding Debounce in JavaScript!

Hey LinkedIn fam! ?? Ever wondered how to improve the performance of your JavaScript functions, especially when dealing with events like scroll, resize, or input? ?? That's where Debounce comes to the rescue! ??

?? What is Debounce? Debouncing is a programming practice used to ensure that time-consuming tasks do not fire so often, making your application more efficient and responsive.

?? How does it work? When an event is triggered, debounce introduces a delay before executing the associated function. If another event occurs within that delay, the timer resets. This way, the function only gets called after a certain quiet period, preventing unnecessary execution and optimizing performance.

?? Why use Debounce? Whether you're handling user input or responding to window resize events, debounce can significantly reduce the number of function calls, making your application smoother and more responsive.

?? Code Snippet Example:

const inputField = document.getElementById("input-field");

// Example of debounce function
function debounce(func, delay) {
  let timeoutId;
  return function (input) {
    clearTimeout(timeoutId);
    timeoutId = setTimeout(() => {
      func(input);
    }, delay);
  }
}

const debounceClosure = debounce((input) => {
  console.log(`Make API call and search for ${input}`)
}, 2000);

inputField.addEventListener("input", () => debounceClosure(inputField.value));        

?? Takeaway: Next time you're dealing with resource-intensive functions, consider implementing debounce to optimize your JavaScript code and enhance user experience. Happy coding! ???
