arktsperf

HarmonyOS ArkTS performance notes, small examples, and arktsperf-lint (pure Node, zero npm deps). ArkTS is TypeScript-like; the checker accepts .ets, .ts, and .js.

Part of XPerf. Shared docs: docs/README.md. Corpus-ready (AGENT.md G3). Defaults: at-includes-hot and at-json-hot hint; at-alloc-hot and at-console-hot off. at-object-delete was removed after a Node proxy stayed about 1×. Guide v0 scaffold.

FocusCopy Anchor Link

Embed / mini-program-like constraints: hot allocation, polymorphic object shapes, and sync bridge / console chatter on the UI or worker hot path. at-console-hot (console.* in loop) defaults to off after G3 (sample noise); enable with --severity at-console-hot=hint. Claims without a device or local bench stay provisional. corpus-ready: yes — see docs/corpus.md.
