Can you use it with spaces on either side? " — " ...? I was taught without spaces when used between words.

Yeah, I use them often... This is the exact shortcut I use as well, it's become second nature.

I also find myself using them in SMS texts. Just long press "-" on my mobile's virtual keyboard.

This does not need:
1. dockerfiles.
2. all package manager, should be inferred which one you're using..
3. runtime specific configs, should infer bun or node..

Something is amiss

Like its soooo good, I actually thought I typed an "m". Here it is with an extra "r" in front just to show how good the "rn" worked:

Additional notes for context:
- For a small backend user interface component within Wordpress.
- I do have a fallback in place if unpkg.com is unreachable.
- I did not have the time to recreate what I needed in vanilla js.
- I miss SFC 😔.

My kids would love this! What software/app was this created with?
