You can use both ways to justify your answer

let section = document.getElementsByTagName('section')[0];
section.addEventListener('click', (e) => {
  if (e.target.tagName == "INPUT") {
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
}
});

let section = document.getElementsByTagName('section')[0];
section.addEventListener('click', (e) => {
if (e.target.tagName != "INPUT") return;
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';
});
