Isso é necessário — você tem que criar uma função assíncrona para definir o bloco de código no qual você executará seu código assíncrono; como falamos mais cedo, <code>await</code> só funciona dentro de funções assíncronas.</p> - + <p>Dentro da definição da função <code>myFetch()</code> você pode ver que o código se parece muito à versão anterior com promise, , mas tem algumas diferenças. Ao invés de precisar encadear um bloco <code>.then()</code> no final de cada método baseado em promise, você apenas adiciona a palavra-chave <code>await</code> antes de cada chamada de método, e então atribui o resultado a variável. A palavra-chave <code>await</code> faz com que o JavaScript pause seu código em tempo de execução nesta linha, não permitindo mais nenhum código ser executado nesse meio tempo até que a chamada de função assíncrona retorne seu resultado — muito útil se o código subsequente depender desse resultado!</p> - + <p>Assim que estiver completo, seu código continua a ser executado começando na próxima linha. Por exemplo:</p> - + <div class="code-example"><pre class="brush: js notranslate"><code><span class="token keyword">let</span> response <span class="token operator">=</span> <span class="token keyword">await</span> <span class="token function">fetch</span><span class="token punctuation">(</span><span class="token string">'coffee.jpg'</span><span class="token punctuation">)</span><span class="token punctuation">;</span></code></pre></div> - + <p>A resposta retornada pela promise <code>fetch()</code> preenchida é atribuída a variável <code>response</code> quando a resposta estiver disponível, e o parser pausa nesta linha até que isso ocorra. Uma vez que a resposta está disponível, o parser move para a próxima linha, o qual cria o <code><a href="/pt-BR/docs/Web/API/Blob">Blob</a></code> fora dele. Esta linha também invoca um método assíncrono baseado em promise, assim podemos usar <code>await</code> aqui também. Quando o resultado da operação retorna, retornamos isso fora da funcão <code>myFetch()</code>.</p> - + <p>Isso significa que quando nós chamamos a função <code>myFetch()</code>, isso retorna uma promise, então podemos encadear um <code>.then()</code> no final, dentro do qual lidamos com a exibição do blob na tela.</p> - + <p>Provavelmente você já está pensando "isso é realmente demais!", e você está certo — menos blocos <code>.then()</code> para envolver o código, e quase sempre se parece com um código síncrono, por isso é muito intuitivo.</p> </div> - + <h3 id="adding_error_handling">Adicionando tratamento de erros</h3> - + <div> <p>E se você deseja adicionar tratamento de erros, você tem algumas opções.</p> - + <p>Você pode usar uma estrutura <code><a href="/pt-BR/docs/Web/JavaScript/Reference/Statements/try...catch">try...catch</a></code> síncrona com <code>async</code>/<code>await</code>.
