Ternary Operator

The ternary operator is a simplified conditional operator like if / else.

Syntax: condition ? <expression if true> : <expression if false>

Here is an example using if / else:

if (authenticated) {
  renderApp();
} else {
  renderLogin();
}

Here is the same example using a ternary operator:

authenticated ? renderApp() : renderLogin();

blue  renderBlue()  renderRed();
