We trend towards using many small open-source libraries which are essentially undocumented these days. The average case seems to be a README with a few examples rather than a clear API specification. Digging through Stack Overflow is essentially looking for someone who has already reverse engineered the exposed API in a library so you don’t have to. If projects were documented — like, actually documented, not just a cursory README — we would all be able to program without the internet. Honestly, it’s much easier than the way things are now.
