title: Why this regex does split second double quote but not first double quote?
body: <p>I have this regex:</p>
  
  <pre><code>let regex = /(?=\.|[\"])/;
  test = "\"test.test\""
  test.split(regex)
  </code></pre>
  
  <p>which outputs:</p>
  
  <pre><code>[""test", ".test", """]
  </code></pre>
  
  <p>whereas I want </p>
  
  <pre><code>[""", "test", ".test", """]
  </code></pre>
  
  <p>I can't see why it splits second double quote but not first double quote</p>
  
  <p>P.S.: must keep ".test" like that (and not "." "test")</p>
