<h3>Definição e uso</h3>
<p class="description">
A tag <script> é usada para **inserir ou referenciar código JavaScript** em páginas HTML5.
Pode ser colocada dentro do <head> ou do <body> e suporta tanto scripts internos quanto externos.
<br>
<mark>Scripts internos são escritos entre <script> e </script>, enquanto scripts externos usam o atributo <code>src</code>.</mark>
</p>
</section>
<section class="example-section">
<h3>Estrutura Básica</h3>
<p class="description">
Sintaxe para script interno: <br>
<code><script>console.log('Olá Mundo');</script></code> <br><br>
Sintaxe para script externo: <br>
<code><script src="script.js"></script></code>
</p>
</section>
<section class="example-section">
<h3>Exemplo 1: Script interno</h3>
<div class="code-block">
<script><br>
alert('Bem-vindo ao site!');<br>
</script>
</div>
<h3>Exemplo 2: Script externo</h3>
<div class="code-block">
<script src="utils/js/app.js"></script>
</div>

<section class="example-section">
<h3>Exemplo 3: Script no final do <body></h3>
<p class="description">
É uma prática comum colocar scripts no final do <body> para melhorar o carregamento da página:
</p>
<div class="code-block">
<body><br>
<h1>Minha Página</h1><br>
<script src="utils/js/app.js"></script><br>
</body>
</div>
