New Nullish Coalescing Operator ?? - the better ||

I just wanted to point out that this year we got access to the Nullish Coalescing Operator '??'. This will skip over the left argument ONLY when it is null or undefined, not when it is a falsey value like false or zero. This should come in super handy when checking for only undefined and nulls, i.e. empty or incorrect inputs. Happy coding!
