With Hermes engine, certain date formats crash on production but works in debug

React Native version: RN60

new Date(‘Jul 18, 2018’) is not supported on RN new Date(‘18-07-2018 12:00’) is not supported on RN

Steps To Reproduce

1. add date: const reproduce = new Date(‘Jul 18, 2018’);
2. It will crash in production

Describe what you expected to happen: It should return the expected date.

Snack, code example, screenshot, or link to a repository:

export function getDateFormat(date = ‘Jul 18, 2018’ ) { const newDate = new Date(date); return newDate; }

export function getDateFormat(date = ‘18-07-2018 12:00’ ) { const newDate = new Date(date); return newDate; }

I’m seeing this also. A date in ISO format like Fri, 06 Sep 2019 18:45:29 +0000 (UTC) parses as an Invalid Date in Hermes. It works on iOS and was working in Android in 0.59. I am now using Moment as a workaround but this should be supported natively.
