As the name indicates ternary operators take three operands. The syntax is condition ? result1 : result2;.
Here you use a condition before question mark (?) followed by result 1 and result 2 separated by a colon (:). Result1 is called if the condition is satisfied else result2 is called.The ternary operator will accept three operands and is used to assign a certain value to a variable based on a condition. The ?: operator can be used as a shortcut for an if…else statement. It is typically used as part of a larger expression where an if…else statement would be awkward. For example:
condition ? result1 : result2;
var now = new Date(); var greeting = "Good" + ((now.getHours() < 17) ? " evening." : " day.");
The example creates a string containing “Good evening.” if it is after 6pm. The equivalent code using an if…else statement would look as follows:
var now = new Date(); var greeting = "Good"; if (now.getHours() > 17) greeting += " evening."; else greeting += " day.";DOWNLOAD SOLUTION HERE
