The listener is not filtering out the tagname

Question

code: let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {

if(e.target.tagName =='input'){ e.target.style.backgroundColor = 'rgb(255, 255, 0)';

} });

I'm not sure what's wrong with (e.target.tagName =='input') or (e.target=='input') isn't working

app.js

let section = document.getElementsByTagName('section')[0];

section.addEventListener('click', (e) => {

if(e.target.tagName =='input'){
  e.target.style.backgroundColor = 'rgb(255, 255, 0)';

}
});

Hi Evan,

The target tagName that you'll find in event (e) is always uppercase, so right now it's not working because it's giving uppercase and you're comparing to lowercase. Try changing "input" to "INPUT" and see how it goes!
