what's wrong here I made everything correct

here is the Bummer hat was told: (Bummer! You didn't log out the even numbers from 2 to 24)

for ( var i = 2; i <= 12; i += 1 ) {
console.log( i )

Hi there! You have a good start, and your syntax is spot on but it's not doing what you think it's doing. It should be printing out all even numbers between 2 and 24 (inclusive). However, your code prints out all numbers between 2 and 12 (inclusive). It's even printing out the odd ones. I encourage you to run your code in the console and take a look at what it's producing.

I wrote it like this:

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

This starts our count with 2 and goes up to 24 (inclusive). Then we increment by two each time (as opposed to 1).

Hope this clarifies things! :sparkles:


Almost there.

for (var i = 2; i < 25; i += 2) {

This sets i to 2. Then loops +=2 until it is less than 25. Hope this helps

Happy coding


it isn't 25 it is 24 though but thanks for your support too :)

Yeah. Mine works also but I think Jennifers is best practice though. :)

Yes, your does work and I don't believe either one of ours is really "best practice". I'm of the opinion that it doesn't matter. I was just attempting to keep the code as close to the original as possible :smiley:

Thank you both for your support :)

Happy Coding
