Following is the code, which is working fine - 

const print = x => {
  console.log(x)
}


const result = [1,2,3,4].forEach(print)
console.log(result)

But when I am trying to pass another variable to print2 function I am getting an undefined error.

const print2 = (x, y) => {
  console.log(x * y)
}

const result = [1,2,3,4].forEach(print2(x, 10))
console.log(result)

I am going through the callback function chapter, so please spare me if something very common I missed here.

    Use `.forEach(x => print2(x, 10))`. And note that `forEach` does not return anything, your `result` variable is thus undefined. – str May 28 '20 at 14:20
