    var inp = document.getElementById(‘inp‘),
        timer = 0;
    inp.oninput = function (e) {
        var val = e.target.value;
        var f = function () {
            alert(val)
        }

        if (val === ‘‘) {
            f = function () {
                console.log(‘setState = []‘);
            }
        }

        clearTimeout(timer);
        timer = setTimeout(function () {
                f();
        }, 400);
    }
