    constructor(props) {

        this.state = {
            text: "default"
        }
       
    }
   
inputChange=(e)=>{
    this.setState({
        text:e.target.value
    })
}
    
    render() {
        return (
            <div> 
               <input  type="text" value={this.state.text} onChange={this.inputChange}/>
               <p>{this.state.text}</p>
            </div>
