In JavaScript what does for(;;){…} do?

Question

I\'ve seen this in some JavaScript code but I don\'t get what it does.

for(;;){

  //other code

}

I\'m used to the for(i=0;i

for (;;) is the exact same syntax. You're allowed to leave out parts that go between the semicolons, even all of them. If you leave the condition out, it's assumed to be true, so it results in an infinite loop. You can of course still exit with break or return or whatnot, hence making it not useless.
