Is there a null coalescing operator available in JavaScript?
For instance, in C#, I can write:
String someValue = null;
var desiredValue = someValue ?? "Chocolates!";
The closest I’ve found in JavaScript is using the ternary conditional operator:
let someValue = null;
let desiredValue = someValue ? someValue : 'Chocolates!';
This seems a bit cumbersome to me. Is there a more straightforward way to achieve this in JavaScript?
"Hey there! JavaScript has a neat feature called the nullish coalescing operator (??
) which you might find handy! It works similarly to the C# example you mentioned. Here’s how you can use it:
let someValue = null;
let desiredValue = someValue ?? 'Chocolates!';
In this example, desiredValue
will be 'Chocolates!'
because someValue
is null
. This operator checks for null
or undefined
and can simplify your code quite a bit. I’ve found it super useful when setting default values. Hope this makes your coding easier!

Hey there! Try the nullish coalescing operator (??
):
let someValue = null;
let desiredValue = someValue ?? 'Chocolates!';
Quick and straightforward!
Here’s a fresh take on your question:
In JavaScript, if you’re dealing with null
or undefined
and need a fallback value, the nullish coalescing operator (??
) is your best friend. It makes handling default values a breeze without complex logic:
let someValue = null;
let desiredValue = someValue ?? 'Chocolates!';
In this example, when someValue
is null
or undefined
, desiredValue
becomes 'Chocolates!'
. This approach simplifies default value assignments and is more concise than using the ternary operator. It’s an efficient way to write cleaner and more readable JavaScript code.
