Get contact email in checkout via JavaScript

[TomCalmigo]

Hi all,

I want to collect some data in the checkout funnel.

What I am looking for is the contact info in the shipping and payment phase, how can I get that via JavaScript ript?

For example if I want to know the current step that the user is in the checkout funnel I check Shopify.Checkout.step in the JavaScript Console.
The yellow line is what I want to get "test@test.com"

Thanks
