title: Fetch API request timeout?
body: <p>I have a <code>fetch-api</code> <code>POST</code> request:</p>
  <pre><code>fetch(url, {
    method: 'POST',
    body: formData,
    credentials: 'include'
  })
  </code></pre>
  <p>I want to know what is the default timeout for this? and how can we set it to a particular value like 3 seconds or indefinite seconds?</p>
