3,486 PointsJavaScript Help.... again please
I have really struggled with JavaScript Loops. Can someone help me with this final challenge. 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.
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);

You will want to use a for loop for this challenge. You would set your initial variable to 2, run the loop as long as the variable to less than 25 (because you want it to go to 24) and then increment the variable by 2. Inside the loop, you will want to use console.log to output the variable.
for (var i = 2; i < 25; i += 2) {
console.log(i);
}
I hope that makes sense. Keep Coding! :)

3,486 PointsThank you so much. I do not understand why i am struggling so bad with JavaScript. I will likely have to take Loops and even basic JavaScript over again... but right now I am on a script completion timeline for what i am doing. Thanks though. :-)
