This command <span class="highlight">displays</span> all the packages installed in your Node.js project in a <strong>tree structure</strong>! 📋

<p style="margin-bottom: 20px;">
Think of it like opening your closet to see all your clothes organized by category! 👔 It shows you every package, along with their dependencies, in a beautiful hierarchical view!

<strong>Breaking It Down:</strong>
<ul style="margin-left: 30px; margin-top: 10px; line-height: 2;">
<li><code>npm</code> - Node Package Manager</li>

<div class="steps">
<div class="step">
<h3>Step 1: Reads package.json</h3>
<p>npm checks your package.json for all declared dependencies.</p>
</div>
<div class="step">
<h3>Step 2: Scans node_modules</h3>
<p>It explores the node_modules folder to see what's actually installed.</p>
</div>
<div class="step">
<h3>Step 3: Builds Dependency Tree</h3>
<p>Creates a hierarchical structure showing package relationships.</p>
</div>
<div class="step">
<h3>Step 4: Displays Results</h3>
<p>Shows the tree with package names, versions, and dependencies!</p>
</div>
<div class="step">
<h3>Step 5: Complete!</h3>
<p>You now see your entire dependency structure! 🎉</p>
