74. Typed Array length

The code outputs:

3
10

Explanation:

• The first console.log(arr1.length) statement logs 3 because the MyArray class extends Uint8Array and overrides its length getter method to always return 3.
• The second console.log(arr2.length) statement logs 10 because it creates a regular Uint8Array instance with a length of 10, and the default implementation of length for Uint8Array simply returns the length of the instance.
