Parallel and sequential, especially at the command level, are really the wrong abstractions for running scripts. If you have multiple packages, each with builds, there's a high chance you have dependencies and multiple packages depending on common ones.
What you really want is a way for scripts to describe their dependencies, and then the runner figures out what order to run them in, and cache scripts that don't need to be run because their inputs didn't change.
Wireit[1] is an npm script runner that adds that incrementally on top of package.json. I can't manage an npm monorepo without it now.
Deno started integrating the idea directly into their built-in script runner. I think this is an important enough feature that more runtimes should follow Deno's lead.

DAG + content-addressing, final binary being the target and everything resolved from there. We could have some beautiful build system that just works and is fast, but seems it never magically appears by itself although it seems so elegant. Guess Nix/NixOS is the closest we've gotten so far, works well enough, missing concurrency and parallelism though.
Could you clarify what you mean about Nix missing concurrency and parallelism? I often run builds using nix-output-monitor and it definitely looks like things are running in parallel, although I could be mistaken.
Wireit does both DAG and content-addressing. It figerprints the inputs and outputs of dependencies. And you run scripts externally with plain `npm run` commands. It's really beautiful.
But now we would need each script to independently do their own caching, which isn’t all bad. At least you have more cross runner compatibility and resilience
Genuine question out of curiosity. Why do I want parallel and sequential when I can just write a simple bash script to accomplish the same thing? Is there some additional complexity I’m missing?
As a note here, there are a lot of resources that make bash seem incredibly arcane, with custom functions often recommended. But a simple interruptible script to run things in parallel can be as simple as:
(To oversimplify: The trap propagates the signal (with 'kill') to the process group 0 made by the () parens; this only needs to be set at the top level. & means run in background, && means run and continue only on success.)
There are other reasons one might not want to depend on bash, but it's not something to be afraid of!
I get where you're coming from and if this was a package I'd agree - but having this built in/part of the tooling is nice - one less dependency - bash isn't as ubiquitous as you assume.
This is cleaner and you don't have to write a bash script. It's one (well, several: the script, bash, and it's dependencies) less thing, which is important in containers and for scale.
Is it more common in English to use there terms Parallel and Sequential or Parallel and Series ?
Made a React Library to generate video as code and named two components <Parallel> <Series> I was wondering if those were two best terms two use...
Electric engineering talks about parallel and series. (including the old parallel and serial ports on computers, before almost everything became serial)
Programming talks about parallelism or concurrency or threading. (single-threading, multi-threading)
Or synchronous and asynchronous.
The legal system talks about concurrent and consecutive.
Process descriptions might use "sequential" rather than consecutive or series.
"Linear" is another possibility, but it's overloaded since it's often used in reference to mathematics.
Both would be understood and are roughly interchangeable.
"Sequential" feels more appropriate to me for the task runner scenario where we wait for one task to finish before running the next.
"Series" suggests a kind of concurrency to me because of the electrical circuit context, where the outputs of one are flowing into the next, but both are running concurrently. Processes that are Unix piped into each other would be another thing that feels more like a "series" than a "sequence".
When talking in terms of software parallelism, "parallel" and "sequential" are more common to describe, for example, multi-threaded vs. single-threaded implementations.
Series would be perfectly fine, though out of context it might be a bit confusing because it's also used to describe data on a chart.
Using the singular "Sequence" might also be appropriate for a component name, as the component represents the collection entity, rather than referring directly to the things within the collection itself (which I presume are either a prop or the children of the component).
The electronics terms parallel and series are about static physical connections (things are connected in parallel or series — the more grammatical form would be in a series).
The software terms parallel and sequential are about the temporal relationship of activities (things are done in parallel or sequentially). That’s why in software we also have the term “concurrent” which means something different from “parallel”.
I think your average person knows what sequential means but might not remember what series means. Personally I always remember the meaning of series in “parallel vs series” because it must be the opposite of parallel. I’m not proud of the fact that I always forget and have to re-intuit the meaning every time, but the only time I ever see “series” is when people are talking about a TV show or electronics.
Sequential is a fuzzier word. It can imply that a series of steps feeds output from step A into step B and so on. But at the same time it can also drift into areas typically defined as linearization. Where a task runs in parallel but applies in series, in sequence.
Well, that speeds things up a lot. But I agree with spankalee, it should be a DAG.
< "ci": "CI=true bun run check && bun run test && bun run build && bun run docs && bun run zip && bun run zip:firefox"
> "ci": "CI=true bun run --parallel check test build docs && bun run --parallel zip zip:firefox"
Going 1.0 was a requirement for cashing out, don't worry about it. And segfaults don't really even matter as long as you run the code in production with -OReleaseSafe and turn on ubsan, it's fiiiiineee
This is nice to see, but I'm curious to check if the web socket bugs are all gone (I had a watch on a particular one that stopped me from running Node-RED in some circumstances, but can't find it on mobile...)
It's fascinating to see a project like Bun, already mature enough to run in production, and yet still improving everyday even if it's a 1.1x speedup. To me, that shows how committed the team is to deliver performance.

Git bash exists on windows and is perfectly usable.
Seriously, my number one windows shell is WSL. Distant second and third are cmd and powershell which I only use to diagnose WSL issue.
At this point you don't need most things...
1. Minor speed boost from not needing bun multiple times (or extract the build/test/lint commands from package.json).
2. You can query/filter commands. E.g. run all my tests (both unit and integration).
3.You avoid needing a separate Bash install (for Windows).

"scripts":{ "buldrun":"run-p check test docs && run-p zip zip:firefox" }
I guess you can put `bun run --parallel` into the script too but it's a bit more verbose.
I’m genuinely curious because there’s currently 63 open issues of reported segfaults.
