Optional chaining operator in JavaScript
With optional chaining being supported in most browsers, it is now easier to parse complex objects.
Previously, developers would resort to using either short-circuits or nested if statements in which they would compare against undefined.
Now, it is even easier (and cleaner!) to accomplish the same validation with the optional chaining operator.
Even better, you can even use optional chaining with expressions using bracket notation, or, if you have a deeply nested object, you can stack optional chaining operators to check for deeper properties.
