This is probably really silly but I'm just looking at this code and having absolutely no clue. I'm going back over the videos now but any help would be appreciated.
console.log(2);
console.log(4);
console.log(6);
console.log(8);
console.log(10);
console.log(12);
console.log(14);
console.log(16);
console.log(18);
console.log(20);
console.log(22);
console.log(24);

for(var i=2; i<=24; i+=2) {
console.log(i);
}

i = 2 while i < 25 console.log(i) add 2 to i end
this will do the same thing as all those console logs while reducing your code immeasurably. (If you use 24 instead of 25, your last print of 24 won't get printed, conversely you could do the add at the beginning, start with i=0 instead and then <24 will work)
