The ?? operator was added to TypeScript 3.7 back in November 2019. And more recently, the ?? operator was included in ES2020, which is supported by Node 14 (released in April 2020).
When the nullish coalescing operator ?? is supported, I typically use it instead of the OR operator || (unless there's a good reason not to). What is the ?: (question mark and colon operator aka. conditional or "ternary") operator and how can I use it?
