 <p>async/await을 사용하는데 브라우저 지원이 걱정되는 경우 <a href="https://babeljs.io/">BabelJS</a> 라이브러리를 사용하는 것을 고려해 볼 수 있습니다. BabelJS는 최신 자바스크립트를 사용하여 애플리케이션을 작성하고 사용자 브라우저에 필요한 변경사항을 Babel이 파악할 수 있도록 지원합니다. async/await를 지원하지 않는 브라우저를 만나면 Babel은 이전 브라우저에서 작동하는 polyfill를 자동으로 제공합니다.</p>

   <h3 id="but_how_does_it_work">Mas como isso funciona?</h3>
-  
+
   <div>
     <p>Você notará que empacotamos o código dentro de uma função, e incluímos a palavra-chave <code>async</code> antes da palavra-chave<code>function</code>. 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 &nbsp;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>

     <p>Isso ocorre porque o bloco <code>.catch()</code> vai pegar os erros que ocorrem em ambos, na chamada de função com async e com cadeia de promises.

     <p>Async/await faz seu código parecer síncrono e, de certa forma, faz com que se comporte de maneira mais síncrona. A palavra-chave <code>await</code> bloqueia a execução de todo o código que o segue até que a promise seja cumprida, exatamente como faria com uma operação síncrona.

     <p>Como resultado, seu código pode ser retardado por um número significativo de promises aguardadas acontecendo uma após a outra. Cada <code>await</code> vai esperar que o anterior termine, ao passo que, na verdade, o que você pode querer é que as promises comecem a ser processadas simultaneamente, como fariam se não estivéssemos usando async/await.</p>

Ambos começam com uma função promise personalizada que simula um processo assíncrono com uma chamada <code><a href="/en-US/docs/Web/API/WindowOrWorkerGlobalScope/setTimeout">setTimeout()</a></code>:</p>

     <p>Isso é a função <code>timeTest()</code> que difere em cada caso.</p>

     <p>No exemplo <code>slow-async-await.html</code>, <code>timeTest()</code> se parece com isso:</p>

     <p>Aqui esperamos diretamente todas as três chamadas <code>timeoutPromise()</code>, fazendo cada uma a cada 3 segundos. Cada chamada subsequente é forçada a esperar até que a última termine — se você executar o primeiro exemplo, você verá a caixa de alerta relatando um tempo total de execução de cerca de 9 segundos.</p>

     <p>Aqui nós armazenamos os três objetos <code>Promise</code> em variáveis, que tem o efeito de desencadear seus processos associados, todos rodando simultaneamente.</p>
-

     <p>A seguir, aguardamos seus resultados — porque todas as promises começaram a ser processadas essencialmente ao mesmo tempo, as promises serão cumpridas todas ao mesmo tempo; ao executar o segundo exemplo, você verá a caixa de alerta relatando um tempo total de execução de pouco mais de 3 segundos!</p>

     <p>Como nota final, antes de prosseguirmos, você pode até adicionar <code>async</code> na frente de métodos de classe / objeto para fazê-los retornar promises, e <code>await</code> promises dentro deles. Dê uma olhada no artigo <a href="/pt-BR/docs/Learn/JavaScript/Objects/Inheritance#ecmascript_2015_classes">Código de classe ES que vimos em nosso JavaScript orientado a objetos</a>. em seguida, olhe para nossa versão modificada com um método <code>async</code>:</p>

     <p>Uma consideração ao decidir se deve usar async/await é o suporte para navegadores mais antigos. Eles estão disponíveis em versões modernas da maioria dos navegadores, o mesmo que promises; os principais problemas de suporte vêm com o Internet Explorer e o Opera Mini.</p>

     <p>Se você deseja usar async/await, mas está preocupado com o suporte a navegadores mais antigos, pode considerar o uso da biblioteca <a href="https://babeljs.io/" class="external" rel=" noopener">BabelJS</a> — isso permite que você escreva seus aplicativos usando o JavaScript mais recente e deixe Babel descobrir quais mudanças, se houver, são necessárias para os navegadores de seu usuário. Ao encontrar um navegador que não suporta async/await, o polyfill do Babel pode fornecer automaticamente substitutos que funcionam em navegadores mais antigos.</p>
