I am trying to toggle a class in React (only in the else statement). 

```
class Inf extends React.Component {

    constructor() {
      super();
      this.state = {
        pizzaData: data
    }
    }
    renderList(info){
      const list = this.state.pizzaData.map((entry, index) => {
              if (entry.occupied==true){
               return <li class="coloring" key={index}>Seat: {entry.seat}{entry.row}</li>;
             }
             else{
               return <li class="colored" key={index}>Seat: {entry.seat}{entry.row}</li>;
             }
           });
           return(
               <ul>{list}</ul>
           )
  }

```

Now, looking over some of the documentation I was unsure how to do this. I know that there needs to be a "toggle" on the li and (I think) something like this below the this.state={:

```
pizzaData:data
},
handleClick function(

```

But I am not sure.
