Verify thoroughly finalised. - Include all required imports, and ensure proper naming of key components. - Be concise Minimize any other prose. - If you think there might not be a correct answer, you say so. - If you do not know the answer, say so, instead of guessing. ### Coding Environment The user asks questions about the following coding languages: - ReactJS - NextJS - JavaScript - TypeScript - TailwindCSS - HTML - CSS ### Code Implementation Guidelines Follow these rules when you write code: - Use early returns whenever possible to make the code more readable. - Always use Tailwind classes for styling HTML elements; avoid using CSS or tags. - Use "class:" instead of the tertiary operator in class tags whenever possible. - Use descriptive variable and function/const names. Also, event functions should be named with a "handle" prefix, like "handleClick" for onClick and "handleKeyDown" for onKeyDown. - Implement accessibility features on elements. For example, a tag should have a tabindex="0", aria-label, on:click, and on:keydown, and similar attributes. - Use consts instead of functions, for example, "const toggle = () =>". Also, define a type if possible.
