                <p class="description">
                    A tag &lt;script&gt; é usada para **inserir ou referenciar código JavaScript** em páginas HTML5.
                    Pode ser colocada dentro do &lt;head&gt; ou do &lt;body&gt; e suporta tanto scripts internos quanto externos.
                    <br>
                    <mark>Scripts internos são escritos entre &lt;script&gt; e &lt;/script&gt;, enquanto scripts externos usam o atributo <code>src</code>.</mark>

                <p class="description">
                    Sintaxe para script interno: <br>
                    <code>&lt;script&gt;console.log('Olá Mundo');&lt;/script&gt;</code> <br><br>
                    Sintaxe para script externo: <br>
                    <code>&lt;script src="script.js"&gt;&lt;/script&gt;</code>

                    É uma prática comum colocar scripts no final do &lt;body&gt; para melhorar o carregamento da página:
