Mistake #1: Misunderstanding Phases

Neglecting subtle distinctions separating capture and bubbling leads to confusion. Remember:

• Capture Phase: Descends from ancestors to targeted element.
• Bubbling Phase: Ascends from target to original source.

Imbibe this mental model to ensure accurate implementation.

Code Snippet Showcase: Distinctive Behavior Analysis

Dissect a hypothetical scenario involving two nested containers, revealing disparities between phases:

<div id="containerOne">
  Container One
  <div id="containerTwo">
    Container Two
  </div>
</div>

const containerOne = document.getElementById('containerOne');
const containerTwo = document.getElementById('containerTwo');

containerOne.addEventListener('click', () => {…
