Example

• This function helps a lot when you are calling some function lots of time but you only need to call it when it should be called.

• Like when user is typing in a input box and you want to make it so that when user stops typing for a while, you send a request to the server for some data fetching.

const debounce = require("@helper-modules/debounce");

const callback = (msg) => {
    console.log(msg);
}

const debouncedCallback = debounce(callback, 2000);

let interval = setInterval(() => {
    console.log("interval");
    debouncedCallback("callback called");
}, 500);

setTimeout(() => {
    console.log("clearing interval")
    clearInterval(interval);
}, 3000);
