keyup nach x Sekunden lesen

For example you like to request something after you ve typed something, but first after x-secondes we sent a request.

let input = document.getElementById('input');
let timeout = null;

input.addEventListener('keyup', function (e) {
    clearTimeout(timeout);
    timeout = setTimeout(function () {
        console.log('Value:', input.value);
    }, 1000);
});
