Add Concept Exercise for type checking.

[quintuple-mallard]

This PR adds the assembly-line exercise and type-checking concept to the JavaScript track.

A few notes/questions:

• I have noticed that some other tracks (C#, Go, and Ruby (and possibly more)) already have an exercise called Assembly Line, all on the numbers concept, but all slightly different. Does this matter?
• An error with nodejs that I haven't been able to fix has stopped me from running the format script. Configlet and the other node scripts have been working.
• The concept teaches Object.hasOwn rather than Object.prototype.hasOwnProperty, as it seems Object.hasOwn is the recommended over Object.prototype.hasOwnProperty, that is considered somewhat outdated.
• I have been coding via GitHub's online editor, often for only a few minutes, so there are quite a few very small commits.

A response to your questions @quintuple-mallard

This PR adds the assembly-line exercise and type-checking concept to the JavaScript track.

A few notes/questions:

• I have noticed that some other tracks (C#, Go, and Ruby (and possibly more)) already have an exercise called Assembly Line, all on the numbers concept, but all slightly different. Does this matter?

Yes, somewhere on the website (cannot find it now) there is a page that shows exercise information + which tracks implement it. There should be no problem with overloading the name of an exercise, but for clarity and to ensure that that page doesn't break, we should slightly change the story. Perhaps we just call this recycling-robot and use the exact same story but then for recycling material?

• An error with nodejs that I haven't been able to fix has stopped me from running the format script. Configlet and the other node scripts have been working.

What is the error? I can also format for you by typing /format here (an action will now run to format using the CI).

• The concept teaches Object.hasOwn rather than Object.prototype.hasOwnProperty, as it seems Object.hasOwn is the recommended over Object.prototype.hasOwnProperty, that is considered somewhat outdated.

That is correct! Times have changed.

• I have been coding via GitHub's online editor, often for only a few minutes, so there are quite a few very small commits.

Sounds fine; we will squash at the end, so make as many commits as you want.

The "Format code" action has started running.

[SleeplessByte]

Ah. Format on the CI doesn't run because your branch is called main ;). I'll fix the format once you're done. Just ping me @quintuple-mallard

[quintuple-mallard]

I have renamed the exercise to Recycling Robot.

Here is the "Format code" script output:

/home/[username]/Documents/GitHub/javascript
/home/[username]/Documents/GitHub/javascript/node_modules/.pnpm/[email protected]/node_modules/prettier

[format] corepack pnpm dlx [email protected]/node_modules/prettier --write "**/*.{js,jsx,cjs,mjs,ts,tsx,css,sass,scss,html,json,md,yml}"
 ENOENT  ENOENT: no such file or directory, open '/home/[username]/.cache/pnpm/dlx/neavhuhbszfrs6ovixsvauyx5e/197bfebc68f-21ad/node_modules/prettier/package.json'

Sorry for the closing and reopening, that came from me trying to rename the main branch.

@SleeplessByte I managed to format it by switching to Windows and running the script.
Possibly the issue came from me using Xubuntu, or missing something I had installed on Windows?

Yeah weird. The format of what command it's trying to run is off I think. I think it should have been:

corepack pnpm dlx [email protected] --write "**/*.{js,jsx,cjs,mjs,ts,tsx,css,sass,scss,html,json,md,yml}"

But 🤷🏽

[quintuple-mallard]

somewhere on the website (cannot find it now) there is a page that shows exercise information + which tracks implement it.

I think it is exercism.org/exercises/<exercise-slug> (e.g. https://exercism.org/exercises/bob) (unless there is a different one I don't know of). It throws a 500 error for Concept Exercises though.

That's it!

I'll have an in depth review for you by the weekend. Thanks for working on this, am excited!
