The "?" seems to be called the conditional operator.

var points = prompt('How many points do you want on ten?');
var result = (points >= 5) ? "succeeded!" : "didn't succeed ;-)";
window.alert("You " + result);

This is called a ternary operator. As the name indicates ternary operators take three operands. The syntax is condition ? result1 : result2;
It is often used as a shortcut for an if..else statement.
