How to use setState in React

Issue #662

Use spread operator

import React, { Component, useState, useEffect } from 'react';

const [state, setState] = useState({
        message: '',
        chats: [],
        sending: false
})

setState(prevState => ({ 
    ...prevState,
    message: '',
    sending: false
}))
