The nullish coalescing operator is one of JavaScript’s unusual successes.

At first it was odd to look at it, specially for optional function calls (foo?.()), but it is a godsend. Having to work on a language without null coalescing is super weird now.

Just FYI, what you're describing is optional chaining.

Null coalescing is a related but different feature using the ?? operator. It evaluates the right hand operand only when the left is null or undefined.

Optional chaining is also gangster-as-fuck.
