Nullish Coalescing Operator

Today I learned that javascript gained a nullish coalescing operator (??) in ECMAScript 2020.

const result = potentialEmpty ?? fallbackValue;

It return the right operand if the left operand is null or undefined so for me this is a convenient alternative to using the OR (||) operator if I don’t want the fallbackValue on falsy values like 0 or an empty string.
