I thought that was a practical example ;)

You can use 'a = b = c = 42' whenever you want to assign the same value
to more than one variable or property. The values will be assigned from
right to left:
  - precedence made explicit: a = (b = (c = 42))
  - the expression c = 42 is evaluated first, and returns 42
  - that result is assigned to b, and the assignment returns 42 again
  - that result is then assigned to a

If you do this with variables, be careful to declare them first. This is
a common mistake:

  function makeRedBlock () {
      var color = "red",
          height = 20,
          width = length = 10;
      //...
   }

This will assign the values as intended, but 'length' has not been
declared and will end up as a global.
