Edit Question
Title
Body
I have an array with permissions from Facebook and an array of the permissions that the user shouldve given: window.FB.api('/me/permissions', function(perm){ if(perm){ var given_permissions = _.keys(perm['data'][0]; var needed_permissions = ["publish_stream", "email"]; //now check if given permissions contains needed permissions } } Now I want to compare if all the needed_permissions are in given_permissions , in an underscore savvy way (without looping two arrays myself and compare values). I saw a _.include method, but this compares an array with a value. I want to return true if all the permissions are available and else a false. I was looking for a nice single line call if possible. The reason for this is, that FB.login returns true even if the user chooses to cancel the extended permissions. So I need to doublecheck this.
