What is a ternary operator in JavaScript?

The ternary operator, also known as the conditional operator, is a shorthand way of writing an if-else statement in JavaScript. It takes three operands: a condition followed by a question mark (?), a value to be returned if the condition is true, followed by a colon(:), and a value to be returned if the condition is false.

Here is an example of how the ternary operator works:


var x = 10;
var result = (x > 5) ? 'x is greater than 5' : 'x is less than or equal to 5';
console.log(result);


In this example, if the condition x > 5 is true, the value 'x is greater than 5' is returned, otherwise the value 'x is less than or equal to 5' is returned.

The ternary operator can be a useful tool for writing concise and readable code. It is often used in combination with other operators or functions to perform complex logic in a single line of code.

Overall, the ternary operator is a powerful feature of JavaScript that allows for efficient and expressive conditional statements.
