Whenever you see something you don't recognize, that just might be part of
Javascript you didn't know about, try checking with one of the Javascript
reference sites. I'm sure there are a few opinions which is 'best', but I
just check the Mozilla site, such as searching for "mdn javascript foreach"
with Google which gets you to Array.prototype.forEach()
<https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach?redirectlocale=en-US&redirectslug=JavaScript%2FReference%2FGlobal_Objects%2FArray%2FforEach>
But what you have cited seems to be missing a callback reference, like
list.foreach( function(file){
if file.ext = ext then {
console.log(item[i]
}
});
Can you look at that "official answer" again?
