is there a way to append a component using react?

Question

Basically i would like the user to click a button which will add a <Message /> component to the page. and they can keep clicking the button and more <Message /> components will be created.

Pseudo Code

render() {
    return (
        <button onClick={this.addMessage}></button>
        <Message />
        //basically a new message component would spawn here so it would look like this if the person clicked the button 3 times

        <Message /> 
        <Message /> 
        <Message /> 

    );

}

addMessage = () => {
   create new Message component
}

Hint... every click adds to an array in state and you then map that array in the render() and each iteration creates a new <Message/> — charlietfl

As @charlietfl says, each action by the user sets a new array with one extra item in it :) — Icepickle

Use a state object to do what you want. For example,

const [messages, setMessages] = useState([]);
const wasClick = (data) => {
    setMessages([...messages, data]);
}

and then in render function

messages.map(message=><Message message={message}/>)
