I just took a stab at git worktree at work this week after rereading this article. It’s amazing. We were in the process of upgrading our UI component library and I was able to checkout pre/post upgrade branches without having to continuously npm install to swap between dependencies.

Plus I’m pretty sure I could have both “versions” of our repo locally running at the same time so I could do UI comparisons…but I didn’t actually get that far.
