How to write users into an array from the form in state?

Question

JavaScript

Tell me how to correctly form an array with users (list) entered through the form in the state to send it to the server?

class SignIn extends Component {
  state = {
    name: "",
    organization: "",
    email: "",
    current:"",
    phone: "",
    simulator: "",
    error: "",
    list: []
  };
  componentDidMount() {
    auth.logout();
  }

  handleChange = e => {
    const { name, value } = e.target;
    this.setState({ [name]: value });


  };
  onSubmit = e => {
    e.preventDefault();
    const { name } = this.state;
    localStorage.clear();
    localStorage.setItem("userName", name);
    const local = localStorage.getItem("userName");
  };

  render() {
    const { classes } = this.props;
    return (
        <main className={classes.main}>
          <CssBaseline />
          <Paper className={classes.paper}>
          <form className={classes.form} onSubmit={this.onSubmit}>
              <FormControl margin="normal" required fullWidth>
