bench: replace new Array(100) with zeros(100, 'generic') in assert/is-*-property benchmarks

[Planeshifter]

Description

Propagating fixes merged to develop between 2026-05-08 17:03 PDT and 2026-05-09 02:24 PDT to sibling packages with the same defect.

6f01b40 — replace new Array(100) with zeros(100, 'generic') in assert/is-*-property benchmarks

Mirrors 6f01b40 across 19 benchmark files: replaces new Array( 100 ) with zeros( 100, 'generic' ) and adds the corresponding @stdlib/array/zeros require after the isBoolean import, resolving stdlib/no-new-array violations. The arr variable serves only as a property-inspection target, so zero-initialization is semantically equivalent to uninitialized. For is-readable-property-in, the inline // eslint-disable-line stdlib/no-new-array suppression directive is also removed alongside the violation it masked.

Validation

• Search scope: each source pattern was searched within lib/node_modules/@stdlib/**/test/*.js and lib/node_modules/@stdlib/**/benchmark/*.js. Originating packages already fixed by the source commits (assert/is-readable-property) were excluded.
• Independent validation: two independent Opus validation agents reviewed every candidate site by reading each file in full; both returned confirmed for all 19 P2 sites. A separate Opus adaptation agent generated the per-site P2 patches (import-after-anchor + line replace), and a Sonnet style-consistency agent confirmed each replacement matches the source-commit precedent.
• Deliberately excluded:
  • The blank-line removals propagated from 41d54f5 and 6f01b40 (originally bundled with this PR) were dropped after reviewer feedback: the empty lines separating fixture import blocks are intentional logical-group separators (e.g., column_major_* vs row_major_*), not stray whitespace. See discussion at bench: replace new Array(100) with zeros(100, 'generic') in assert/is-*-property benchmarks #12010 (comment).
  • 01ddffb2 ("docs: propagate recent fixes across stats/base/dists and lapack/base") — itself a propagation commit; recent-merge dedup applies.
  • f7b9386 ("docs: place copy in codeblock") — one-off editorial fix to docs/contributing/zen_of_stdlib.md with no replicable search signature.
  • 88 files matched by the new Array(N) regex but rejected: math/strided/special/*-by, math/strided/ops/*-by, strided/base/*-by, and stats/strided/*-by test files use new Array(5) to construct intentionally sparse arrays — replacing with zeros(5, 'generic') would change test semantics (callbacks skip holes but would process zero-valued slots).
  • assert/is-prototype-of/benchmark.js and assert/is-arraybuffer-view/test/*.js — new Array(N) used as a value in a heterogeneous-type-dispatch literal; replacement would change the runtime type observed by the type-checking function.
  • stats/{fligner,bartlett,kruskal}-test, stats/{ttest2,vartest,binomial-test,chi2gof}, blas/base/gasum, array/pool, and several utils/* benchmark files — arrays fully overwritten in a fill loop before any read; the Array constructor here triggers the lint rule but the values are not semantically uninitialized.

Disclosure

This PR was authored by Claude Code as part of a routine that scans recent develop commits for generalizable fixes and propagates them to sibling packages. Each propagation site was independently verified by two Opus validation agents, an Opus adaptation agent (for the new Array → zeros substitution), and a Sonnet style-consistency agent before patches were applied. The changes are mechanical analogs of the cited source commits and touch only benchmark setup.
