I'm a starter and not sure how I should write this piece of code properly, since 'event' seems deprecated.
input.addEventListener("keydown", () => {
if (event.keyCode === 13) {
event.preventDefault();
button.click();
}
})
You missed an event in the callback
input.addEventListener("keydown", (event) => {
if (event.keyCode === 13) {
event.preventDefault();
button.click();
}
})
