title: Automatically convert string concatenation to template literals
body: <p>I have a code base with many strings built via string concatenation. Is there a automated method for replacing all instances of string concatenation with <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals" rel="nofollow noreferrer">templates</a>? For example:</p>
  
  <pre><code>const a = 'b ' + c;
  // becomes:
  const a = `b ${c}`;
  </code></pre>
  
  <p>A script-based solution would be awesome. An editor plugin would be even better. (I am using Visual Studio Code.)</p>
