Solution

To create a simple component in React, you can follow these steps:

  1. Option 1:

    • Define a class called HelloMessage.
    • Inside the class, create a render() method.
    • In the render() method, return the JSX code for the component, which includes a <div> element with the text "Hello" followed by the value of the name prop.
    • Use the this.props.name syntax to access the value of the name prop.
    • Close the render() method and the HelloMessage class.

  2. Option 2:

    • Define a class called HelloMessage that extends React.Component.
    • Inside the class, create a render() method.
    • In the render() method, return the JSX code for the component, which includes a <div> element with the text "Hello" followed by the value of the name prop.
    • Use the this.props.name syntax to access the value of the name prop.
    • Close the render() method and the HelloMessage class.

  3. Option 3:

    • Define a class called HelloMessage that extends React.Component.
    • Inside the class, create a render() method.
    • In the render() method, return the JSX code for the component, which includes a <div> element with the text "Hello" followed by the value of the name prop.
    • Use the this.props.name syntax to access the value of the name prop.
    • Close the render() method and the HelloMessage class.

  4. Option 4:

    • Define a class called HelloMessage that extends React.Component.
    • Inside the class, create a render() method.
    • In the render() method, return the JSX code for the component, which includes a <div> element with the text "Hello" followed by the value of the name prop.
    • Use the this.props.name syntax to access the value of the name prop.
    • Close the render() method and the HelloMessage class.

After defining the component, you can use the ReactDOM.render() method to render the component on the page. Pass the component element <HelloMessage name="Taylor" /> as the first argument and the target element's ID (hello-example) as the second argument to ReactDOM.render().

Note: Option 3 is the correct way to create a simple component in React.
