HTML vs. JSX Differences:

Sure, here are some key differences between HTML and JSX:

1. Syntax: In HTML, you use a specific set of tags such as <div>, <span>, <p>, etc. to define elements. In JSX, you can use JavaScript expressions inside curly braces {} along with these tags.

2. Naming Conventions: HTML uses kebab-case (e.g., data-id) for attribute names, while JSX uses camelCase (e.g., dataId).

3. Self-closing Tags: In HTML, tags like <img>, <input>, and <br> can be left open, but in JSX, all tags must be closed, either with a closing tag (e.g., </div>) or self-closed (e.g., <img />).

4. JavaScript Integration: JSX allows you to directly embed JavaScript expressions and variables in your markup, which is not possible in HTML.

5. Component Creation: JSX allows you to create and use your own components, which is a powerful feature not available in HTML.

6. Runtime: HTML is a markup language and runs in the browser. JSX is not a language, but a syntax extension for JavaScript, and it needs to be compiled into JavaScript before it can run in the browser.
