JavaScript JavaScript and the DOM (Retiring) Responding to User Interaction Event Delegation

How do I select input Items only

Have been trying to solve this one but can't get the right solution!

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)';
  }
});
index.html
<!DOCTYPE html>
<html>
    <head>
        <title>JavaScript and the DOM</title>
    </head>
    <link rel="stylesheet" href="style.css" />
    <body>
        <section>

You just have a small error in that you need to use the conditional "==" as opposed to a singe equal sign which is an assignment operator.

if(e.target.tagName == "INPUT") {

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

section.addEventListener('click', (e) => {
    if(e.target.tagName == "INPUT") {  // Test if current element is an input element
        e.target.style.backgroundColor = 'rgb(255, 255, 0)';
    }
});

Thank You so much!
