Modern array and object methods produce code that directly expresses intent — a filter() call self-documents that you're selecting items. Manual for loops obscure the purpose behind implementation details. These methods are also well-optimized by JavaScript engines and support chaining for concise data transformations.
Find loops in this file that could be replaced with modern array methods like map, filter, reduce, find, or flatMap.
Replace manual for/while loops with appropriate array methods to make the code more declarative.
Explain map, filter, reduce, find, flatMap, and Object.entries with practical examples.
Review scripts, client components, and browser execution paths related to Use modern array and object methods. Flag exact imports, event handlers, runtime side effects, or blocking operations that violate the rule, and state how the change should be verified in the browser.

概要と使いどころ
Use when reviewing templates, rendered HTML, or shared components related to Create a custom 404 error page. Validate the final browser-facing markup, not just the source framework abstraction.

Use when auditing metadata, crawlability, structured data, or indexability related to Create a dedicated About page. Verify the rendered HTML and HTTP response rather than relying only on source files.

Use when reviewing component libraries, page flows, or CI pipelines that need repeatable accessibility checks. Automated testing is strongest at catching structural and attribute-level issues; it does not replace keyboard, screen reader, and manual UX testing.

Use when reviewing sign-in, sign-up, MFA, CAPTCHA, recovery, and re-auth flows. Evaluate the full authentication path, including error handling and backup methods, not just the primary login form.

Use when reviewing rendered HTML, interactive components, or design-system patterns related to Use semantic table markup for screen readers. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
