It's a great site, of course, but lists don't make good submissions to HN. The comments will be about the lowest common denominator of the items on the list, and this is usually pretty generic.<p>It would be better to pick one of the most interesting items on the list and submit that instead.<p><a href="https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sort=byDate&type=comment&query=denominator%20lists%20by:dang" rel="nofollow noreferrer">https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...</a>
If a language fits into a familiar paradigm, the absolute fastest way to learn, I've found, is to whip open the LXY page and docs, and translate a known quantity such as Advent of Code or a personal toy project.
"Learn" is meaningless with cheatsheets like this. There's much more to a language than its syntax, and I'm afraid that's the part one can't have a cheatsheet for.<p>For this reason, I never tried LXiYM for Common Lisp/Racket/Clojure because actually lisping in those languages involves a new way of thinking, not knowing a new notation.
One of the best resources online IMHO. I always wondered if the original intent was to have a number of different “Y”, ie separate tutorials to choose from: learn c in 10 minutes and learn c in 30, etc.
I see Jira is not listed among the tools you can learn in Y minutes. I assume because it's not possible to learn Jira in minutes, even an arbitrarily large number of them...
