Answer 1

In vanilla javaScript - in ES6

(() => {
    document.querySelector('.parent').addEventListener('click', event => {
        alert(event.target.classList.contains('child') ? 'Child element.' : 'Parent element.');
    });
})();

.parent {
    display: inline-block;
    padding: 45px;
    background: lightgreen;
}
.child {
    width: 120px;
    height:60px;
    background: teal;
}
