What will be the output of console.log(sofia.age) given the current prototype setting?

In JavaScript, when you access a property of an object, the engine checks the object itself for that property first. If it doesn't find it, it will then look up the prototype chain to see if the property is defined there.

In this case, if the output of console.log(sofia.age) is expected to return the value of 29, it implies that the age property is defined on the prototype of the sofia object or on the object itself and holds the value of 29.

If sofia is an object that has been set up correctly to either have age as a direct property or inherit it from its prototype with the value of 29 assigned, calling console.log(sofia.age) will yield that value.

If the sofia object doesn't have an age property defined directly or in its prototype chain, the result would typically be undefined, but since it is specifically stated that the answer is 29, that indicates that access to the property is effectively pulling from whatever the prototype was set to contain.

This aligns with JavaScript's behavior of looking up the prototype chain when accessing properties, confirming that the property exists within the defined structure allowing for the
