Let’s say you have a null variable named ‘a’ with the value null.
var a = null;
In order to set a default value, you can use the nullish coalescing operator
var a = null; console.log(a ?? "a is null");
Note: The nullish coalescing operator
?? is a logical operator that functions by returning the value on its right side if the value on its left side is
undefined. Else, it will return the value on its left side.
