Review: APPROVE (docs only, LOW risk)
This improves the error handling guide by making the error class hierarchy explicit. The changes are accurate:
- Correctly distinguishes
AbortError,FetchError,TypeError,RangeError,SyntaxErroras separate error paths - Clarifies that
FetchErrorwithtype = 'system'wraps Node.js core I/O errors - Removes ambiguous language ("all operational errors other than aborted requests") and replaces with specific class names
- Updates the test file reference (though the link still points to
masterbranch — should bemain)
The rewrite is clearer and more useful than the original. A developer reading this can now write a proper catch block that handles each error type correctly.
Minor: The link to test/main.js still uses the master branch URL. The repo's default branch is main. Not a blocker.
Verdict: Safe to merge. Strictly improves documentation accuracy.
