Returning an array in JavaScript

I am having trouble with one of the challenge questions in the JavaScript form validation section. It says "Create a method called 'requiredValues' that returns an array of all the values of inputs with the class of 'required'.

So I have tried creating a variable:

var $required = $(".required");

 //here first of all I don't know if I should be going $(".required input")//

//Then I tried creating a new array within the method//

function requiredValues(){
var values = new Array();

//here I already don't know if I'm on the right track, but it gets even more fuzzy//
//I try calling 'each' on the variable//

$required.each(function){
values($(this));
});

//I know I need to return something//

return values;
}

Sorry if my syntax here sucks. I know I can get the syntax right, I just need some general direction to put me on the right track. Thank you!

Markdown is done by putting three ` marks at the beginning and end of your code.

It's the symbol at the bottom of the tilde key ~

After the three opening ` marks, write the type of code you're showing : HTML, javascript etc.

You've to push the values:

function requiredValues() {
    var values = new Array();
    $(".required").each(function() {
        values.push($(this).val());
    });
    return values;
}
