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.
