Name specific tools and patterns: "I use eslint-plugin-jsx-a11y in CI, test with axe DevTools, trap focus in modals with a custom hook, and use aria-live for toast notifications."
Key practices: semantic HTML elements, proper ARIA attributes, keyboard navigation, focus management (especially with modals and dynamic content), accessible forms with labels, and colour contrast. Tools: eslint-plugin-jsx-a11y, axe DevTools, screen reader testing. Strong candidates mention specific patterns like focus trapping in modals and live regions for dynamic updates.
Increasingly expected of frontend developers. Candidates who never consider accessibility in React are missing a fundamental skill. Ask for a specific example of an accessibility challenge they solved in a React app.
