Question

A. Class name Question should start with a lowercase q.

B. Keyword final is incorrectly used.
 C. Identifier package is a reserved keyword.
 D. Value true should be all uppercase for constants.

Answer 1

The error in the following code is this: C. Identifier package is a reserved keyword.

What is the error in the code?

Using "package" as an identifier will result in a syntax error. The code will not be interpreted correctly by the JavaScript engine, and the programmer will encounter an error message.

The reason for the above is that the identifier "package" is a reserved keyword in JavaScript which was designated for future use as a keyword in potential language extensions. So, it cannot be used as a variable name, function name, or other identifier in a JavaScript code.
