How can I throttle input events in a React application?

How can I throttle input events in a React application?

You can use the lodash library's throttle function or implement your own throttling logic using setTimeout.

Can you show me an example using lodash?

Sure! First, install lodash with npm install lodash. Then, you can use it like this:

import { throttle } from 'lodash';

const handleInputChange = throttle((event) => {
  console.log(event.target.value);
}, 1000);

<input type="text" onChange={handleInputChange} />

What if I want to implement my own throttling function?

You can create a custom throttle function like this:

function throttle(func, limit) {
  let lastFunc;
  let lastRan;

  return function() {
    const context = this;
    const args = arguments;
    if (!lastRan) {
      func.apply(context, args);
      lastRan = Date.now();
    } else {
      clearTimeout(lastFunc);
      lastFunc = setTimeout(function() {
        if ((Date.now() - lastRan) >= limit) {
          func.apply(context, args);
          lastRan = Date.now();
        }
      }, limit - (Date.now() - lastRan));
    }
  };
}

Thanks! This is really helpful.
