JavaScript if else shorthand | Example code

  • by

You can use the ternary operator as an if-else shorthand in JavaScript. It lets us write shorthand if..else statements exactly as we want.


condition ? exprIfTrue : exprIfFalse


var hasName = (name === 'john') ? 'Y' :'N';

It looks like this:

(name === 'john') – our condition

? – the ternary operator itself

'Y' – the result if the condition evaluates to true

'N' – the result if the condition evaluates to false

JavaScript if else shorthand

Simple example code.

<!DOCTYPE html>

  <script type="text/javascript">
   var age = 26;
   var beverage = (age >= 21) ? "Beer" : "Juice";

Conditional chains

The ternary operator can be “chained” in the following way, similar to a if … else if … else if … else chain:

function example(…) {
    return condition1 ? value1
         : condition2 ? value2
         : condition3 ? value3
         : value4;

// Equivalent to:

function example(…) {
    if (condition1) { return value1; }
    else if (condition2) { return value2; }
    else if (condition3) { return value3; }
    else { return value4; }


How to use shorthand for if/else statement in JavaScript

Answer: To use a shorthand for an if-else statement, use the ternary operator. The ternary operator starts with a condition that is followed by a question mark ?, then a value to return if the condition is truthy, a colon :, and a value to return if the condition is falsy.

const result1 = 10 > 5 ? 'yes' : 'no';
console.log(result1); // 'yes'

const result2 = 10 > 100 ? 'yes' : 'no';
console.log(result2); // 'no'
