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.
var counter = 1;
for (counter = 1; counter <= 12; counter * 2) {
console.log(counter);
}

Treehouse Project ReviewerDon't overthink it. You can simplify this and reduce the code like so:
- You don't need to create a variable outside of the loop, you can use the index variable defined in the loop that you should create
for (var i = 2) in this case. - The initial value of the variable should be 2 since you want to print out from number 2, not 1.
- Your condition's value should be 24, not 12 since you want the loop to end once the value of the variable is 24.
- You don't need to multiply the number, you need to use the
+=operator to add the value on the right to the variable.
for (var i = 2; i <= 24; i += 2) {
console.log(i);
}
