Solution

It seems like you've made a statement rather than asking a question. However, I can provide some clarification based on your statement.

  1. "Hello World!" in JSX: In JSX, which is used in React, you don't necessarily need to enclose strings in curly brackets. You can simply write it like this: <div>Hello World!</div>. However, if you want to evaluate JavaScript expressions within JSX, then you would use curly brackets, like this: <div>{'Hello World!'}</div>.

  2. JSX in <div> tags: Yes, JSX expressions must be wrapped in an enclosing tag. This is because JSX tags must have exactly one parent element. So, if you have multiple JSX elements, they should be wrapped in a single parent element, like a <div>.

  3. Exporting component headline: If by "component headline" you mean the name of the component, then yes, it should not be exported. Only the component itself should be exported. For example, if you have a component named Headline, you would export it like this: export default Headline;.

  4. class vs className: In JSX, you should use className instead of class to add CSS classes to your elements. This is because class is a reserved word in JavaScript. For example, you would do it like this: <div className="myClass">Hello World!</div>.
