The state of semantic JSX

Creating accessible React applications involves implementing semantic code and focus management to enhance user experience, particularly for those using assistive technologies. The text explores how modern JavaScript frameworks, such as React, have transformed web development by breaking down web pages into components, addressing whether this affects web functionality and accessibility. It emphasizes the importance of the POUR principles—Perceivable, Operable, Understandable, Robust—for building accessible websites and examines tools like React Fragments to eliminate unnecessary div tags, thereby ensuring more semantic HTML. Additionally, it discusses focus management through the use of refs to navigate and control user interaction, reinforcing the importance of semantic JSX, and using tools like React accessibility linters for cleaner, more accessible code. The article encourages developers to adopt these practices to create more inclusive web applications.
