A few questions, this is the first TC39 intent I've looked closely at... There are concrete examples of the new things in https://github.com/tc39/proposal-unified-intl-numberformat. Currently, in Chrome 74, the example in "I. Units" throws RangeError, while the example in "II. Scientific and Compact Notation" just returns "987,654,321", which isn't the expected value.
Given this, how should web developers detect support for these new things? Is there a polyfill in Babel? Also, will Chromium be the first browser engine to ship support for this? Are there bugs filed for shipping it in Gecko and WebKit too? Thanks!
