title: How does moment.js determine the locale
body: <p>I am wondering if anyone has a clear idea of how moment.js determines the locale. Does it get it from the browser or the system? I am using <code>moment.format(lll)</code> to show local date formats for different regions. The docs do not appear to be specific about this? There is one section that states locales have to be loaded, but that did not answer my question.</p>
