How to print even numbers using a for loop?

I find this simple "for loop" exercise.

Using a for loop print all even numbers up to and including n. Don’t include 0.
let n1 = 22; 

// Example output: 

// 2 4 6 8 10 12 14 16 18 20 22 OR each item on a new line

I found a way to solve this but I don't think its elegant at all.

Here is my code:

let n1 = 22;

for (let i = 0; i < n1; i++){
    
   let  b = i * 2;

    if (b <= n1){
        if (b == 0) {} else 
        { console.log('Count',b);}
    };
       
};

How can I improve it?

Just count by twos:

for (let i=2; i <= 22; i+=2) {
     console.log('Count', i);
}

for (let i=2; i <= 22; i+=2) {
     console.log(i);
}

all the best

Here using while loop:

const count = { index: 0, n1: 22 }

while(count.index < count.n1) {
  console.log('Count', count.index += 2)
}
