The of Expression


  <expression> of <expression>


The of expression allows you to reverse the normal order of property accessors for clearer code.

So this:

<button _="on click call window.location.refresh()">
  Refresh the Location

Can be rewritten like this:

<button _="on click refresh() the location of the window">
  Refresh the Location

Where we have converted window.location into the form the location of the window.
