  _deleteTodo(index) {
    console.log("delete " + index);
    this.state.todos.splice(index, 1);
    this.setState({
      todos: this.state.todos.filter(i => i !== index)
    });
  }

I had a problem with splice and i honestly don know why. However this method work for me and you can try it! Ps. If anybody know why splice is not working with state and index please let me know i am curious!
