  • It's the [optional chaining operator](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining). – D M Jan 04 '23 at 17:36

The optional chaining (?.) operator accesses an object's property or calls a function. If the object accessed or function called is undefined or null, it returns undefined instead of throwing an error.
