JavaScript

Tell us what’s happening:
My list prints to the screen and works. Looks like a bug stopping me from passing. How can I get it to let me pass. I tried with and without a index key.Thank you.

Your code so far


const textAreaStyles = {
  width: 235,
  margin: 5
};

class MyToDoList extends React.Component {
  constructor(props) {
    super(props);
    // change code below this line
    this.state = {
      toDoList: [],
      userInput : ""
    }
    // change code above this line
    this.handleSubmit = this.handleSubmit.bind(this);
    this.handleChange = this.handleChange.bind(this);
  }
  handleSubmit() {
    const itemsArray = this.state.userInput.split(', ');

    this.setState({
      toDoList: itemsArray
    });
  }
  handleChange(e) {
    this.setState({
      userInput: e.target.value
    });

  }

  render() {
    const items = this.state.toDoList.map((item, index) =>  <li key={index}>{item}</li>); 
    return (
      <div>
        <textarea
          onChange={this.handleChange}
          value={this.state.userInput}
          style={textAreaStyles}
          placeholder="Separate Items With Commas" /><br />
        <button onClick={this.handleSubmit}>Create List</button>
        <h1>My "To Do" List:</h1>
        <ul>
         {items}
        </ul>
      </div>
    );
  }
};

I’m showing a list of items like in your example and I’m changing the split and still getting a list but still not passing. Thank you for look at it randelldawson.

const itemsArray = this.state.userInput.split(", ");

The instructions say type a word with comma separated. That is what I’m doing and it is rendering correctly maybe I need to try a different browser I’m using Chrome.

const itemsArray = this.state.userInput.split(",");
