: Excellent semantic HTML improvements!Converting the generic

:⚠️ Potential issueGreat performance optimization with memoization!
Converting the
SkillCards
component to useReact.memo()
prevents unnecessary re-renders, which is a valuable performance optimization. The use of semantic<article>
tags and proper<h3>
headings for card titles also improves accessibility.One issue:
React is imported but flagged as unused by ESLint. For memoized components, you need to keep the React import:
-import React, { memo } from "react"; +import React from "react"; +import { memo } from "react";Likely an incorrect or invalid review comment.

: Great accessibility and performance improvements in SkillCards!The changes to this component follow best practices:
- Memoization to prevent unnecessary re-renders
- Semantic
<article>
tag instead of generic<div>
- Proper heading hierarchy with
<h3>
aria-hidden="true"
for decorative iconsThese improvements enhance both accessibility and performance.
21-46
: Excellent updates to CoursesCardThe accessibility improvements are well-implemented:
- Using React.memo for performance optimization
- Converting to semantic
<article>
tag- Proper heading hierarchy with
<h3>
- Making decorative icons hidden from screen readers
I see you've also removed the invalid
loading="lazy"
attribute from the button element that was flagged in previous reviews. Good job!
72-83
: Good optimization for CTACardYou've successfully implemented React.memo for performance optimization and improved the conditional rendering with the nullish coalescing operator.
Note that this component still uses a
<div>
rather than an<article>
tag as its container, unlike the other card components. Is this intentional? If it serves as a container for other content rather than being standalone content itself, then a<div>
may be appropriate.
85-109
: Great accessibility improvements in WhatOurUsersSayThis component has been nicely improved with:
- Memoization for better performance
- Semantic
<article>
tag- Proper heading hierarchy with
<h3>
- Decorative quote icon correctly marked with
aria-hidden="true"
These changes align perfectly with the PR objectives for performance and accessibility enhancements.
