📝 Walkthrough

Walkthrough

The changes correct guard documentation, API examples, and test expectations across utility packages. They clarify primitive and object behavior, document enumerable property checks for empty objects, and update the ArrayBufferView typed-array list. A Changeset declares patch releases for four packages.

Changes

API contract corrections

Layer / File(s)	Summary
Primitive guard contracts and examples packages/util-core/src/guards/*, packages/util-core/test/guards/*, packages/util-number/src/guards/*, packages/util/test/helpers/assert-value.ts, .changeset/correct-api-examples.md	Documentation and examples distinguish primitive values from boxed values for the BigInt, Boolean, Number, String, and Symbol guards. Tests check rejection of boxed values. The assertValue failure-message expectations use “String primitive.” The Changeset declares patch releases for four packages.
Object-like and empty-object descriptions packages/util-core/src/guards/is-object-like.ts, packages/util-object/src/guards/is-empty-object.ts, packages/util-object/test/guards/is-empty-object.ts	The isObjectLike description includes functions. The isEmptyObject description covers properties visited by for...in, including inherited enumerable properties. Tests cover inherited enumerable, symbol-keyed, and non-enumerable properties.
ArrayBufferView documentation and example packages/util-types/src/guards/is-array-buffer-view.ts, packages/util-types/test/guards/is-array-buffer-view.ts	The documentation distinguishes DataView from typed arrays and adds typed-array names. The example and test expect BigUint64Array to be recognized.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other · Severity of issue fixed: Low

Merge Risk: 🔵 Low · up to 77d35

The isObjectLike example now shows functions as accepted, while the return description omits them. Updating the wording would keep the API documentation consistent; the issue is localized and does not affect runtime behavior.

- Around line 10-11: Update the `isEmptyObject` return documentation to describe
the observable `for...in` behavior: return `false` when the loop finds an
enumerable string-keyed property and `true` otherwise, accounting for shadowing
by non-enumerable own properties.

🟡 Minor · Update the @returns description to include functions. · is-object-like.ts:32-37

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Update the @returns description to include functions.

isObjectLike accepts functions, but @returns still describes only objects. This makes the API contract inconsistent with the implementation and example.

Suggested fix

- * @returns `true` if `value` is an object; else, `false`.
+ * @returns `true` if `value` is an object or function; else, `false`.
