Ternary operator is also known as the conditional operator because it evaluates a condition and returns one of two values based on the result of the condition.

Syntax

The syntax of the ternary operator is as follows:

condition ? value1 : value2;

The condition is evaluated first. If the condition is true, value1 is returned; otherwise, value2 is returned.

Examples

Here are some examples of using the ternary operator in JavaScript:

let x = 10;

let result = x > 5 ? "greater than 5" : "less than or equal to 5";

console.log(result); // "greater than 5"

In this example, if x is greater than 5, the value of result will be "greater than 5"; otherwise, it will be "less than or equal to 5".

let y = 3;

let message = y % 2 === 0 ? "even" : "odd";

console.log(message); // "odd"

In this example, if y is even (i.e., y % 2 === 0 is true), the value of message will be "even"; otherwise, it will be "odd".

Conclusion

• The ternary operator is a shorthand way of writing an "if-else" statement in JavaScript.
• It is often used to assign a value to a variable based on a condition.
• The syntax of the ternary operator is condition ? value1 : value2.
• The condition is evaluated first, and if it is true, value1 is returned; otherwise, value2 is returned.
