What will be the log output for the following code snippet?

In the given code snippet, if the output is logged as "Undefined," it implies that a certain variable or property was accessed that has not been defined or initialized prior to the log statement.

In JavaScript, when a variable that has been declared but not assigned a value is accessed, it will return undefined. For instance, if the code tried to access a variable named name that was declared but not given a value, logging that variable would yield "Undefined."

Another common scenario for seeing "Undefined" logged would be if your code attempted to access an object property that does not exist. If the object is well-formed but lacks the specific key in question, it will yield undefined since JavaScript allows for a safe retrieval of properties regardless of their existence.

In contrast, if the code involved a properly defined variable or function returning a value, you would see either the actual value (like "Test" or "John") or potentially an error like a "TypeError" if there was an issue performing operations on undefined values. Because "TypeError" typically occurs when trying to call methods on undefined or an incompatible variable type, it is less likely unless specific faulty operations were attempted.

Therefore, in this case
