React - Expected an assignment or function call and instead saw an expression failed to compile

So I have this TODO List App with laravel backend and React and when I nom start my React App it shows me this:

./src/List.js
  Line 126:  Expected an assignment or function call and instead saw an expression  no-unused-expressions

Search for the keywords to learn more about each error.

Anyone have idea why is this happening? I tried everything but nothing happens, and I'm new to React, I followed tutorial for this with Laravel API routes and React js frontend

Here is my List.js:

import React, { Component } from "react";
import { getList, addItem, deleteItem, updateItem } from "./ListFunctions";

class List extends Component {
  constructor() {
    super();
    this.state({
      id: "",
      title: "",
      editDisabled: false,
      items: []
    });
    this.onSubmit = this.onSubmit.bind(this);
    this.onChange = this.onChange.bind(this);
  }
  componentDidMount() {
    this.getAll();
  }
  onChange = e => {
    this.setState({
      [e.target.name]: e.target.value
    });
  };
  getAll = () => {
    getList().then(data => {
      this.setState(
        {
          title: "",
          items: [...data]
        },
        () => {
          console.log(this.state.items);
        }
      );
    });
  };

  onSubmit = e => {
    e.preventDefault();
    addItem(this.state.title).then(() => {
      this.getAll();
    });
    this.setState({
      title: ""
    });
  };

  onUpdate = e => {
    e.preventDefault();
    addItem(this.state.title, this.state.id).then(() => {
      this.getAll();
    });
    this.setState({
      title: "",
      editDisabled: ""
    });
    this.getAll();
  };

  onEdit = (itemid, e) => {
    e.preventDefault();

    var data = [...this.state.items];
    data.forEach((item, index) => {
      if (item._id === itemid) {
        this.setState({
          id: item.id,
          title: item.title,
          editDisabled: true
        });
      }
    });
  };

  onDelete = (val, e) => {
    e.preventDefault();
    deleteItem(val);
    this.getAll();
  };

  render() {
    return (
      <div className="col-md-12">
        <form onSubmit={this.onSubmit}>
          <div className="form-group">
            <label htmlFor="title">Title</label>
            <div className="row">

          {!this.state.editDisabled ? (

        </form>
        <table className="table">
          <tbody>
            {this.state.items.map((item, index) => {

                </td>
              </tr>;
            })}
          </tbody>
        </table>
      </div>
    );
  }
}

export default List;

And Line 126: is the line after

          <tbody>
            {this.state.items.map((item, index) => {

That is line 126. Please help
