Question 169353 in Javascript Question posted in
A very good W3school tutorial can be found here.

Is there a way to increment count by 1 when it’s a multiple of 2 in Javascript?

How can I increase the value stored in count by one every time it is a multiple of 2

I have a function that returns the value of i, it is initialized to 0 and it is auto-incrementing, that is, when i is a multiple of 2, the counter has to increases by 1

I try to do is that when i is a multiple of 2, the variable count has to increase in 1

This is the code I’m doing, could you tell me where my error is?

let count = 0;
        
if( i % 2  == 0){               
  count++;
  console.log(count);       
}else{

}

    You should divide count by 2, not i

    let count = 0;

if( count % 2 == 0){
    count++; console.log(count);    
}else{

}

    By the way, your code only runs once. So it seems that your code lacks some sort of a loop. There needs to be a for or while loop.

    Update:

    based on your comments, I think your code should look like this:

    let count = 0;
let i = 0;
// set a limit, for example 100
while(i < 100){
  i = updateI(); // get the new value for i
  if( i % 2 == 0)
  {
     count++; console.log(count);    
  }else{

  }
}

    Maybe the full script like this. it works fine

    let count = 0;
let i = 0;
while(i < 10){
  i++;
  if(i % 2 == 0){    
    count++
    console.log('even number',i, 'of',count);       
  }
}
