-Most modern browsers already have ECMAScript Internationalization API support built-in, but many older browsers do not. For these unsupported browsers, Luxon would fail to load the formatted dates on many of the explorer pages which would cause a cascading effect of not loading other data leading to a broken experience. A polyfilled version of Intl.js is now being loaded into the site which will only be downloaded when using a browser that does not already have Internationalization API support
