consider this code

```
class page1 extends React.Component {
  render() {
    const admin = false;

    return (
    <div>

        <button onClick={this.deleteThis}>hello</button>
        <button onClick={this.deleteThis}>hello</button>
        <button onClick={this.deleteThis}>hello</button>
        <button onClick={this.deleteEverything}>hello</button>

    </div>

 );
  }
}

```

Whenever the variable admin is false I don't want to see any button. I could do {admin ? button : null} but my issue with that is i would have to repeat admin several times in my actual code. Is there a one-liner that deactivates every button if admin is false?
