JavaScript in browsers is "single-threaded" (and thank goodness for
that). So when JavaScript is running (in most browsers) everything
else is queuing up. When you break the code into chunks, via
setTimeout, you are (essentially) "yielding" control back to the main
event loop periodically, so it has time to "breath" and clear it
various queues.
