Whether that's true about React and Moment varies on a case-by-case basis.

If you're building something simple like a contact form React may not be the right choice. If you're building something like Trello that calculation is different.

Likewise, I wouldn't want Moment for https://tools.simonwillison.net/california-clock-change but I might want it for something that needs its more advanced features.
