   Insert screaming here.

   An infinite loop, with no library calls whatsoever, gets a system call inserted. That's a horrible surprise waiting to happen.

   The entire concept of the "forward progress guarantee" is broken. An infinite loop should compile to an infinite loop. Nothing more, nothing less.

      But the compilers have to optimize the crap code in big tech codebases by 0.5%, it saves a lot of money.

      Also performance doesn't matter that much and developer time is more important btw, keep using react.

         performance doesn't matter.... so datacenters would be equally happy running software that runs half as fast but uses 10% more power?
