write a simple chat component

[colin-codegen]

The recommended approach involves creating a new simple chat component named SimpleChat. This component uses two state variables, messages, to keep track of the chat history, and newMessage, to hold the new user input. A function handleSend allows the user to send a message and adds a bot response to the chat. The chat interface will consist of a div container which maps over the messages, a text area that captures the user's input and a button with the handleSend attached as an onClick event. The code example in the approach shows how to put these together to form a functional simple chat component.
