fix: safe nested travesal in orderArrayBy - #9668
Conversation
📝 WalkthroughWalkthroughThe PR adds Vitest configuration and tests for array utilities. It updates sorting for nested properties, nullish values, type-aware comparisons, descending keys, and non-mutating behavior. ChangesArray utilities
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change prevents crashes when sorting by nested values containing null or undefined, but symbol-valued sort keys may still cause a runtime TypeError. The PR is mergeable with explicit owner awareness or follow-up to narrow supported comparisons and add symbol coverage. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Do not compare untyped key values.
keyA and keyB remain any. A symbol value reaches Line 69, where relational comparison throws TypeError. Resolve nested values as unknown, then narrow supported primitive types before comparison. Add a test for symbol-valued keys.
As per coding guidelines, “TypeScript strict mode enabled; all files must be typed.”

Cover the unverified sorting behavior.
The strings in Lines 35-39 produce the same order without { numeric: true }. Add values such as item2 and item10 to test natural ordering.
Also add tests for the changed toSorted paths in orderGroupedDataByField at packages/utils/src/array.ts Line 157, sortBySelectedFirst at Line 237, and sortByCurrentUserThenSelected at Line 270. Assert output order and the intended mutation contract.
As per coding guidelines, “All features require unit tests using the existing test framework per package.”
