Why isn't the following forEach array loop returning undefined? [closed]

Answer 1

You probably want to use Array.prototype.map:

var hintList = amaList.map(function(item) {
     //do something with item and return the wanted item
});

Array.prototype.forEach doesn't return anything.

Here's an exampe for using forEach:

amaList.forEach(function(item){ 
     console.log(item);
});
