<h2 class="section-title">⚙️ How Does It Work?</h2>
<div class="card">
<p style="margin-bottom: 30px; font-size: 1.1rem;">Let's break down what happens step by step:</p>
<div class="steps">
<div class="step">
<h3>Step 1: Reads package.json</h3>
<p>npm checks your package.json to find lodash in the dependencies list.</p>
</div>
<div class="step">
<h3>Step 2: Removes from package.json</h3>
<p>The lodash entry is deleted from your dependencies or devDependencies.</p>
</div>
<div class="step">
<h3>Step 3: Deletes from node_modules</h3>
<p>The entire lodash folder is removed from node_modules directory.</p>
</div>
<div class="step">
<h3>Step 4: Updates package-lock.json</h3>
<p>The lock file is updated to reflect the removal.</p>
</div>
<div class="step">
<h3>Step 5: Removes Unused Dependencies</h3>
<p>If lodash had dependencies that nothing else uses, they're removed too!</p>
</div>
<div class="step">
<h3>Step 6: Complete!</h3>
<p>Lodash is completely gone from your project! 🎉</p>
</div>
</div>
<div class="success" style="margin-top: 30px;">
<strong>🎉 Done!</strong> Your project is now cleaner and lighter!
