<!-- What Is It -->
<section class="section">
<h2 class="section-title">🤔 What Is This Command?</h2>
<div class="card">
<p style="font-size: 1.2rem; margin-bottom: 20px;">
This command tells Node.js to <span class="highlight">check the syntax</span> of your JavaScript file <strong>without actually running it</strong>! ✅
</p>
<p style="margin-bottom: 20px;">
Think of it like a spell-checker for your code! 📝 It reads through your JavaScript file, looks for syntax errors (like missing brackets or typos), and tells you if something's wrong - all without executing a single line of code!
</p>
<div class="info">
<strong>Breaking It Down:</strong>
<ul style="margin-left: 30px; margin-top: 10px; line-height: 2;">
<li><code>node</code> - The Node.js runtime</li>
<li><code class="code-flag">--check</code> - Flag that means "check syntax only" (also: <code>-c</code>)</li>
<li><code>script.js</code> - Your JavaScript file to validate</li>
<li>No output = ✅ Syntax is perfect!</li>
<li>Error message = ❌ Syntax problem found!</li>
</ul>
</div>
<div style="margin-top: 30px;">
<h3 style="color: var(--accent-pink); margin-bottom: 15px;">Why not just run it? 🔍</h3>
<p>Running code with syntax errors can cause crashes, unwanted side effects, or security issues. Checking syntax first is <strong>safe</strong> and <strong>fast</strong>!</p>

<section class="section">
<h2 class="section-title">⚙️ How Does It Work?</h2>
<div class="card">
<div class="steps">
<div class="step">
<h3>Step 1: Command Parsed</h3>
<p>Node.js reads the --check flag and file path.</p>
</div>
<div class="step">
<h3>Step 2: File Loaded</h3>
<p>The JavaScript file is read into memory.</p>
</div>
<div class="step">
<h3>Step 3: Parsing Phase</h3>
<p>V8 engine parses the code into an Abstract Syntax Tree (AST).</p>
</div>
<div class="step">
<h3>Step 4: Syntax Validation</h3>
<p>Checks for syntax errors: missing brackets, typos, invalid tokens.</p>
</div>
<div class="step">
<h3>Step 5: Report Results</h3>
<p>If errors found, displays error message with line number.</p>
</div>
<div class="step">
<h3>Step 6: Exit</h3>
<p>Exits with code 0 (success) or 1 (error) - no code executed! 🎉</p>

<h2 class="section-title">🚀 Pro Tips</h2>
<div class="card">
<div class="tip">
<strong>Pre-commit hooks</strong> - Add syntax checking to git hooks to prevent bad commits!
</div>
<div class="tip">
<strong>CI/CD integration</strong> - Fail builds early with syntax checks before running tests!

<div class="tip">
<strong>Combine with linters</strong> - Use ESLint for style + --check for syntax = perfect combo!
</div>
<div class="tip">
<strong>Batch checking</strong> - Check entire directories: <code>find src -name "*.js" -exec node -c {} \;</code>
</div>
<div class="tip">
<strong>Editor integration</strong> - Many editors run --check automatically on save!
</div>
<div class="tip">
<strong>npm scripts</strong> - Add <code>"pretest": "node --check src/**/*.js"</code> to catch errors before tests!
