It would be interesting to track the bug rate after this commit and compare it to the bug rate in the Typescript version of the code base.

  I expect they have a very large unit/integration test suite. Rails was the first (or very early pioneers) of doing TDD.

    A very cursory internet search shows that your history is entirely wrong: https://agileforall.com/history-of-tdd-as-told-in-quotes/ https://agileforall.com/history-of-tdd-as-told-in-quotes/ Djikstra proposed the idea in the 1970s. Rails did not in any way pioneer TDD. They were very vocal about it but “[stood] on the shoulders of giants.”

      Sure, everything could probably be tracked back to the good golden years, but who was really doing TDD before Rails? I was doing Java back (during Kent Beck days of XP etc) and although I had heard of JUnit (and even heard Kent Beck preach about this at a conference) and it sounded cool, no team or company I knew was using it seriously. It's only when Rails came around where if (I believe if memory serves me right) the default controller/views generators created tests automatically. Ruby being a dynamic language and no compile step, you couldn't prove correctness before running it, meant you were skating on thin ice if you didn't write tests.

        > “[stood] on the shoulders of giants.” That's pretty much a given. I know someone people that worked at Xerox (when Steve Jobs visited) and they pretty much invented everything. lol. I've been told stories that pretty much technology after Xerox is a derivative from that time. Sure, I take that with a pinch of salt, but I half/mostly believe it.
