I've written in the past about the many quirks of Javascript dates. The good news is that there are plans for an entirely new piece of Javascript functionality to clean up what Date() does wrong. That functionality is called Temporal. In this guide, we'll be covering why Temporal is better than Date(), and how to use it.
Support for Temporal
Temporal is currently a stage 3 proposal which means that although a large portion of its functionality is stable, there may be some changes in the future. As the specification is not stable yet, no browser or backend Javascript has implemented the temporal specification. If you want to try out Temporal today, you can try this polyfill (use with caution in production).
