Question

Right after my script is loaded I am making an Ajax request to get some translations. This should always return after the document is ready since I am loading my scripts at

jQuery's when is not a proper promise. You can force it into one like this:

function documentReady() {
    return Promise.resolve($.when($.ready));
}

Usage:

documentReady().then(function($) { ... });

It happens to resolve with $ so that's kind of convenient too.

Alternative implementation:

function documentReady() {
    return new Promise(r => $(r));
}
