Question

What is conditional operator give suitable example?

Answer 1

The ?: is the conditional operator in JavaScript, which requires three operands, hence it is called the ternary operator. The syntax is

var variablename=(condition) ? value1 : value2;

Working of conditional operator:

First condition will be evaluated, if the condition returns true then the value of the left side of the colon is assigned to the variable otherwise the value of the right side of the colon will be assigned the variable.

For example:
var result=(10>15) ?100 :150;
In the above example, since the condition returns false the value 150 will be assigned to the result.
