Better way to seize values inside loops

for( var i=0; i<20; i++) 
    setTimeout(function(){ 
        console.log(">>> "+i); 
    }, i*100);

So, the code above outputs >>> 19 20 times. To keep i at it's iteration value I'm using a closure:

for(var i=0; i<20; i++)(function(i){
    setTimeout(function(){ 
        console.log(">>> "+i); 
    }, i*100);
}(i));

What's the problem? The problem is loop control statements, continue; I can do with return; but for those times when I need break; code gets counter-intuitive when others try to read it.

So what can I do?
