Nil Coalescing

Definitions

1. An operator (typically `??` in Swift) that unwraps an optional value if it is non-nil, or returns a specified default value otherwise, providing a concise way to handle absent values without explicit if-let or guard statements.

   In plain English: A shorthand that says 'use this value if it exists, otherwise use this backup value instead.'

   Example: "I used nil coalescing to fall back to the user's system locale when their profile language preference is nil."
