forEach is not a function error with JavaScript array

Question

I\'m trying to make a simple loop:

const parent = this.el.parentElement
console.log(parent.children)
parent.children.forEach(child => {
  console.log(chil         


        

Answer 1

That's because parent.children is a NodeList, and it doesn't support the .forEach method (as NodeList is an array like structure but not an array), so try to call it by first converting it to array using

var children = [].slice.call(parent.children);
children.forEach(yourFunc);
