//JSHint brought my attention to the fact that some PERLisms are just not cool in JS anymore...

//This is cool with JSHint:
console.time('if1'); 
for (var i = 0; i < 100000; i++) { 
  if(1) { //nice and safe, and don't even THINK of skipping those {}s, even though you don't need them either...
    console.log(1 + 1); 
  } 
} 
console.timeEnd('if1');

Understanding Integers and Performance in JS

This is just an interactive node session, not really a code snippet.

But it's pretty instructive.
