7,316 PointsLog an even number from 2 to 24 using loop.
The code below logs all of the even numbers from 2 to 24 to the JavaScript console. However, there's a lot of redundant code here. Re-write this using a loop. I can't get the number 12 on the console log. What am I doing wrong with this challenge?
for (var i = 2; i < 15; i++){
console.log(i);
}

Said another way: starting at two, as long as i is less than 25, add two and log the new variable to the screen.
for ( i=2 ; i<25 ; i+=2 ) {
console.log(i);
}

This code worked fine for me
Cary Oldenkott

for ( i = 2; i <= 24; i += 2;) { console.log(i); }
work just as well instead of i < 25?

23,877 Pointsno it's cause you need to add the number 25 like this:
for(i = 2 ; i <= 25 ; i += 2){ console.log(i); }

Courses Plus Student 845 Pointsvery easy
for ( var i = 2 ; i <= 24 ; i++ ) { if ( i % 2 === 0 ) { console.log (i);
}
}

7,510 PointsMost of you are correct, but you're missing the let statement for the 'i'.....
for ( let i=2 ; i<25 ; i+=2 ) {
console.log(i);
}
