I don't get the 'while (true)'

I don't get the 'while (true)' - while what is true? does it declare that the following is true?

Also why does the 'break' stop the while loop if it is inside the if loop?

Thanks First! I get it now, true has the value of true so its like saying if 2+2=4. Nice one.

exactly while(2+2 === 4){ // do something} is equavalent to while(true){ // do something}

A while loop will repeat the code inside of its braces as long as the condition is true. If we say while(true) we're saying: infinitely repeat the code inside the braces. This of course would make any computer crash, so to avoid this, we have to include some kind of stop condition within the loop. something like if a > 2 then break out of the loop.
