118. structuredClone()

The code below outputs the following by console.log:

true
false
true
false

The first console.log statement checks whether the error object is an instance of the Error constructor function, which it is, so true is logged to the console.

The second console.log statement checks whether the error object is an instance of the SyntaxError constructor function, which it is not (even though we manually set the name property to SyntaxError), so false is logged to the console.

The third console.log statement checks whether the clonededError object (which is a clone of the error object using the structuredClone function) is an instance of the Error constructor function, which it is, so true is logged to the console.

The fourth console.log statement checks whether the clonededError object is an instance of the SyntaxError constructor function, which it is not, so false is logged to the console.
