Define an HTML Class in JSX

Define an HTML Class in JSX

---

Problem Explanation

• HTML and JSX may seem that they are exactly the same but there are a few differences between them.
• One of these differences is the naming convention.
• HTML attributes and event references in JSX become camelCase(onclick => onClick).
• There may also be some words reserved in JavaScript.For instance the word "class" cant be use to define HTML classes in JSX.Therefore instead of using "class" you can use "className".

Hints
