Synopsis
The conditional operator. This 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 : statement2This 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"
