Return only the values if not inside the array in for loop

This array contains 1,5,

let numberArray = [1,5];

I’m trying to print numbers from 1 to 280 except for the values inside the numberArray,

 for (let i = 1; i < 281; i++) {
    numberArray.forEach((number) => {
      if (number != i) {
        console.log(i);
      }
    });
  }

I’m expecting the result to be 2,3,4,6,7...280 without printing 1 and 5 in this case. But I get like this,

It prints 2 times each number except 1 and 5. I want to completely omit the values inside the numberArray and print the other values. Really appreciate it if somebody could point me to the bug. Thanks.

>Solution :

It isn’t a bug, your code is doing exactly what you are telling it too.
You have your for loop which happens 280 times and then you have a forEach loop inside that which is happening twice every time the loop goes around. So the Foreach loop is actually happening. 558 times.

You can just use the .includes method to check i doesn’t exist within the numberArray.

 for (let i = 1; i < 281; i++) {
    if(!numberArray.includes(i)){
       console.log(i);
    }
  }
