JSX and conditional

// JSX and conditional
// In JSX, && is commonly used to render an element based on a boolean condition. && works best in conditionals that will sometimes do an action, but other times do nothing at all.

// If the expression on the left of the && evaluates as true, then the JSX on the right of the && will be rendered. If the first expression is false, however, then the JSX to the right of the && will be ignored and not rendered.
// All of the list items will display if
// baby is false and age is above 25
const tasty = (
  <ul>
    <li>Applesauce</li>
    { !baby && <li>Pizza</li> }
    { age > 15 && <li>Brussels Sprouts</li> }
    { age > 20 && <li>Oysters</li> }
    { age > 25 && <li>Grappa</li> }
  </ul>
);
