redundant code solution

Hello,

I don't understand why this code doesn't work even if I put an "IF" condition ?

script.js 
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(let i = 0; i <= 24; i += 2){
  if(i === 24){
    console.log(i);
  }
}

Hey Alpha DIALLO 👋

There are a few small things going on that stops your code from passing this challenge. First off you'll want to replace the provided log statements with your loop, so you can remove all the lines of code before your for loop.

Next up you'll want to remove the conditional you've added. Because of this only 24 will be logged to the console instead of all the even numbers from 2 - 24.

Finally you'll want to have a look at the initial value you're using for i. With it being 0, 0 will also be logged to the console, while you want the logs to start with 2 🙂

After those adjustments your code should look like this and pass the challenge as expected. 

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

Hope this helps to get you going again! 😃
