The author of the article is a contributor to React and the author of Redux. So the disclaimer is valid, because lots of people read his stuff and might expect some React tutorial or whatever.
I did feel that the yellow warning sign was a bit much. There was also a line about it not being for designers. As somebody with both design and engineering backgrounds, I felt less enthusiastic right away — mostly because I dislike buckets being enforced. It encourages people to put themselves into one over the long run, which in turn has a tendency to stunt their progress. It’s also odd when any educational resource (higher ed in the US being a great example) introduces itself by trying to be inaccessible. It feels counter to the professed goal of the institution / article.
Anyways, I guess I felt the comment above is a valid thing to discuss if it could improve other people’s efforts to write similar pieces.
As an aside: ironically, the article is fascinating from a design perspective. Just not the particular bucket of design the author was thinking of when he wrote that line.
Another unintended effect can be contributing to the perception that React is only for people with a strong programming background rather than, say, a11y expertise. I don’t want that either and that’s why I mentioned there are multiple ways to look at React.
Yet another problem is that random things from my posts are sometimes used in interview questions. :-/
I trust a curious reader to ignore the disclaimers and dive in anyway.
But I also wish I didn’t need to put it there and I emptathize with your frustration.
Anyways, thank you for writing the article, it’s really an enjoyable read after a day of wrestling a closed source framework and wishing I could understand how that particular architecture was reasoned about.
Do you think that without the warning, a beginner would deep into the article, and 50 minutes in, he/she would be like 'heeeey, wait a minute! This is not for me! Why didn't he tell me?'
If not, then such a disclaimer is meaningless.
How do I know? Because I have disclaimers here and there that are obvious for most people and still help to reduce the support burden.
I really don't understand your issue here.
Your complaint about it makes it look like you believe the post was written for you personally, with no regard for the wider audience. That's idiotic.
