To do this, we need to combine Node.children with a few other techniques.
We can use Array.from() to turn the NodeList that Node.children returns into an array, and then use the Array.filter() method to remove an elements that don’t match a test we specify.

function childrenMatches (elem, callback) {
return Array.from(elem.children).filter(callback);
