Output:
ReferenceError: Cannot access 'x' before initialization.

Explanation:
In JavaScript, variables declared with let are hoisted but not initialized. When the code tries to log x, JavaScript knows about x due to hoisting but can't access it before initialization within the function scope, causing a ReferenceError.
