The web as a platform is a safe bet. It’s un-versioned by design. That’s the commitment the web makes to you—take advantage of it:

💡 Embrace progressive enhancement to build fast, reliable applications that adapt to your customers’ context;

💡 Write code the leans into the browser, not away from it.

In the last year alone, I have seen two completely different clients in two completely different industries sink months and months into framework upgrades.
