Empty for loop - for(;;)

Question

I was exploring the Google Closure Compiler, and one thing I noticed was that it converts while(true) into for(;;).

Both do hang the browse

Answer 1

There is evaluation algorothm of for loop in Standard ECMA-262 script that says there are only two situations in which loop will end:

1. break statement
2. value of middle statement equal to false, but only if this statement is present, so it doesnt have to be necessary valuated as true (probably in mozilla js engine it is).
