How to access environment variable from rails on your javascript?

Question

I am trying to set up a key system in the application I'm building. I have a code that has this logic:

$('.key-test-button').on('click', function(){
    if ($('.key-test-input').val() === "MYKEYHERE"){
        $('#hidden-div-instructor').show();
    } 
});

And My Idea was to replace "MYKEYHERE" for a hidden value on my code that I would store as a environment variable. I know how to do that for APIs for example, inside rails, but Im not familiar how I could access this variable inside my javascript/jquery script. I would love if someone could give me a insight. Thanks you.

You will need to pass it into the page/js. You could use a .js.erb in the js file for the specific view you're dealing with. — David Hoelzer

As @davidhoelzer mentioned, you can't do this with pure js (as far as I know)... you could, however, change the .js file to .js.erb and use ruby to access/manipulate your environment variable that way.
