Can someone please tell me why am I getting an error?

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

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

The instructions say to "Rewrite (or refactor) the code using a loop.", so what they want is for for you to replace the code with a loop to produce the same output after conversion. Adding a loop after the original code causes it to produce twice as much output.

Another hint is in the error message you get: "Bummer: Your code should call console.log() one time only."
