I'm not sure that's a given. Lots of things have reached worldwide adoption and don't have the reputation that Git has. Bash, for example, is quirks and chaos galore, and I don't think even that has the same level of i

JJ should be compatible with any existing Git server. The project is currently maintained on Github, and I believe all the maintainers use JJ to work on the project itself. At work, I use JJ a lot with repositories hosted on Azure Devops,

I think that's actually one of the nice things about JJ in comparison to many others (such as hg or Pijul): it uses Git essentially like a protocol or standard by which it communicates with other systems (and as a file-system standard,

You can always undo the most recent action using `jj undo`. To undo older actions, the easiest solution is to look for the state you want to get back to in the operations log `jj op log`, and then restore that state directly using `jj op re

I agree that you probably want to keep staging, but one of the advantages of JJ is that staging is just a change* like any other change in your history. There are a couple of different ways that people use JJ, but I normally use the "s

As others have pointed out there's `jj undo` and other tools, but they all rely on the fact that JJ is less mutable than it seems. Internally, JJ is still backed by an append-only tree of commits. You don't normally get to see the

It's a very common mistake! No worries, I always enjoy getting to explain these details to people, I find them really interesting.

By shadow DOM do you mean the virtual DOM? The shadow DOM is also a thing, but it's largely unrelated to web frameworks. The idea behind the virtual DOM is that it's usually easier to render everything in a functional sort of way

One thing that I've learned over time is that if I can't understand why people are taking some particularly obtuse or circuitous route, then that's probably because I don't yet understand what they're doing properly

In addition, the two cases can be toggled on and off using CSS alone, because `display:inline`, `display:block`, and `display:inline-block` all do different things to the two pieces of whitespace: * `display:inline` allows the trailing spac

I did not know you could check them out! But yeah, that really emphasises what I'm saying: there are too many things that are mostly commits but handled in a different way. And I completely agree that this is about the CLI more than t

I'm going to cheat and say I use a different VCS, but I do really like Jujutsu's approach here. It has this idea of mutable commits, so essentially you can check out a commit, and then whenever you change a file, the commit is upd

And there are patterns for that, that allow you to convert a static exclusivity check into a dynamic exclusivity check - something like a mutex, where multiple threads can simultaneously hold a mutex, but only one thread at a time can gain

Unless you encode ownership into the type system, and then you kind of have the best of both worlds: you don't have functions mutating things unexpectedly or by accident, but you can explicitly opt into mutation when it would be benefi

Namespaces are already pretty rarely used - mostly in older codebases in development as modern JS modules were still being developed and worked out. The Typescript compiler, for example, recently put a lot of work into getting rid of namesp

I've started recommending jj as a (git compatible) alternative to git, and one of the things I like about it is that the default action if you run `jj` with no arguments shows the relevant parts of the commit tree and where you are in

All the different configuration you need for Webpack is built-in to Vite. This includes built-in support for a lot of stuff that would come as separate plugins in Webpack (CSS loading, Typescript support, asset bundling, minification, auto

This is incorrect on several points. Firstly, Node's `require` syntax predates the modern JS `import` syntax. It is related to some attempts at the time to create tools that could act like a module system for the browser (in particula

It's worth noting that Node allows two packages to have the same dependency at different versions, which means that `npm i -g` is typically a lot safer than a global `pip install`, because each package will essentially create its own d

A number of countries use this when giving your pin for a credit card or similar (I've noticed it in both Greece and India). I can't help but feel like it's less secure than the default layout - I'm quite good at hiding

Can you describe some of those basics? In my experience, the JS ecosystem is surprisingly good, and most of the issues tend to be due to a lack of experience rather than directly tooling issues. For example, NPM is one of the better package
