You still don't understand it.

1) When you create a loop which will constantly running this will block
UI since JavaScript is not multithreaded and event handlers will not
execute as long as your code is still busy with other things.

2) If you need something which runs all the time independent from any
user input, either create a worker or use setTimeout()/setInterval() to
"emulate" a background process by calling a function every x ms which
executes only one thing at a time.

What fits best for you depends on your application.
