The conditional operator provides a shortcut syntax to an if/else control structure. There are three components to the deployment of this operator: a condition and two statements. If the condition evaluates to true, the first of the statements is executed; if the condition evaluates to false, the second statement is evaluated. The syntax is as follows: `condition` ? `statement1` : `statement2`

You can nest these operators as a way of adding more decision paths within a single statement. In the following syntax, if `conditionA` evaluates to false, `conditionB` is evaluated, and the entire expression returns the value of `statement2` or `statement3` depending on the results of `conditionB`.

This operator is a shortcut in appearance only. It invokes the same internal processing as an if...else construction.

Example

var newColor = (temp > 100) ? "red" : "blue";
