title: Is it possible to destructure onto an existing object? (Javascript ES6)
body: <p>For example if I have two objects: </p>
  
  <pre><code>var foo = {
    x: "bar",
    y: "baz"
  }
  </code></pre>
  
  <p>and </p>
  
  <pre><code>var oof = {}
  </code></pre>
  
  <p>and I wanted to transfer the x and y values from foo to oof. Is there a way to do that using the es6 destructuring syntax?</p>
  
  <p>perhaps something like: </p>
  
  <pre><code>oof{x,y} = foo
  </code></pre>
