What is the output of following code?
const a = false;
const result = a ?? "Hello";
console.log(result);----o----
Output is false.
The nullish coalescing operator (??) is a logical operator that returns its right-hand side operand when its left-hand side operand is null or undefined, and otherwise returns its left-hand side operand.
Default tendency is to return "Hello" because a is false. But ?? is explicitly built for null or undefined.
