Nice way to learn React! For me the tasks could be a bit more clear, especially the first time when I was looking for what I had to do. But I'll definitely try to learn some React this way!

I think that's why it's called react-koan

I've been itching to learn about React but it's difficult to get into. Thanks for making this, it's very useful to me!

I decided to move from learning Angular+Ionic last night to going with React.js+React Native and found this good dump of information from Github https://github.com/enaqx/awesome-react

Looking forward to trying this tutorial right now.

joshgachnang• 11 years ago

Just curious, why did you make the change? I've been building apps in Angular and Ionic for a bit now and haven't played with React yet.

I was expecting something very different from the word "koans". IMO, "React.js exercises" would be a better title for the project.

"exercises" is not hip enough.

A nod to ruby koans (which was probably a nod to another language): https://github.com/neo/ruby_koans

I believe the word they were looking for is https://en.wikipedia.org/wiki/Kata

Hmmm.... googling around, there seems to be a lot of recent "programming koans" that are actually collections of rote exercises rather than lessons in zen enlightenment. Frustrating...

It looks like what happened was that a while back, someone made a very nice set of exercises each presented as a koan and a failing unit test to "meditate upon". Imitators then watered that down to exercises presented as failing unit tests to "meditate upon". Which was later watered down to just exercises...

For a classic example of an actual programming koan, I can only refer to the archive of Doug Bagely's "Functional Programming Koans, in OCaml" http://web.archive.org/web/20041012103936/http://www.bagley.... and, the old favorite teaching the relationship between objects and closures http://people.csail.mit.edu/gregs/ll1-discuss-archive-html/m...

If this is the case, we should appeal to the author's sense of decency.

The concept of 'koan' is far too unique and beautiful to be watered down.

Roodgorf• 11 years ago

I think you're right in the confusion of koan and kata, but unfortunately yes, I have seen a lot of that happening lately (perhaps due to greater awareness of the word from recent popularity of CodeWars[0]?). Interestingly I've only seen this mistake in this direction, I have not seen any koans mislabeled as kata.

What if the word "koan" were understood to mean "excercise"?

Lazare• 11 years ago

Same.

Although apparently the word is misused a lot: http://www.lauradhamilton.com/learn-a-new-programming-langua...

Not sure if this is a fight we can still win.

Outsider's perspective looking in: This is hacker versus cracker all over again.

The setup doesn't appear to be working from a windows/mingw32 environment. (Most npm installers do work in this environment.)

Did you try submitting an issue on GitHub? https://github.com/arkency/reactjs_koans/issues

voter1012• 11 years ago

I just did submit it by my own. Sorry for that hassle.

If you have more detailed error information, I would be glad if you put them into the comments.

I've tried the instructions (npm run setup) on both a Mac and Ubuntu and resulted on several screen-fulls of npm ERR! messages. Again killed my mild curiosity for React.

rossta• 11 years ago

I haven't had a chance to try React.js koans yet, but recently completed a tutorial in the same vein, a "workershopper", from nodeschool.io: https://github.com/tako-black/learnyoureact. As a React.js noob, I found it to be a helpful introduction.

akilism• 11 years ago

Yeah this nodeschool lesson on react is pretty good if you are just getting your feet wet.

I was expecting something about a monk who had to report to two masters at the same time; but as he reported, the state changed, so they were never synced.

These are not the koans I was looking for.

jkoudys• 11 years ago

I think you have this mixed-up with the story where a react developer updates 1 component on the first render, 2 components on the second, 4 components on the third, 8 on the fourth, and so on, until he's rendered a whole chess board.

industriousthou• 11 years ago

Yeah, I would argue that these are kata rather than koan.

edit: changed to plural.
