React.Component<IReactReadWebpartProps, {}> {

  public
constructor(props:
IReactReadWebpartProps,
state:
IReactReadWebpartState){ 

    super(props); 

    this.state
= {  

      items: [ 

        { 

         
"EmployeeName":

Setting the first-class code formatting in your question aside, you are getting the error because the component's state is described like as an empty object in this line

React.Component<IReactReadWebpartProps, {}>

So you probably should define it so typescript will know what to expect. Some type or interfaces that will include items field will do.
