This question has already been answered:

function Alarm(clock) { Clock.call(this, clock); this.clock.querySelector('.set-alarm').onchange = () => { let timer = clock.querySelector('.set-alarm').value.split(':'); let hour = timer[0]; let minute = timer[1]; let second = timer[2]; this.newDate = new Date(0, 0, 0, hour, minute, second).getTime(); }; console.log(second); }

How to get the variable second or this.newDate so that you can output it to console.log?

console.log () inside onchange and everything should work or what kind of perversions with promises / callbacks

 this.clock.querySelector('.set-alarm').onchange = () => { let timer = clock.querySelector('.set-alarm').value.split(':'); let hour = timer[0]; let minute = timer[1]; let second = timer[2]; this.newDate = new Date(0, 0, 0, hour, minute, second).getTime(); console.log(second); };
