Question

What is wrong with this function definition?function Hello();{alert("Hello"); ("Hello on the screen");}

A. The fact that you are outputting the message twice
B. You can't use after using an alert.
C. The semicolon after Hello()

Answer 1

The main error is the misplaced semicolon after the function name, which can cause the function to not be defined properly. A stray string also suggests a missing function call.

Step-by-step explanation:

The issue with the function definition provided is the semicolon placed after the function name and before the opening curly brace. In JavaScript, a semicolon is typically used to terminate statements, but it should not be placed after the closing parenthesis of a function declaration before the opening curly brace. The function should be defined without a semicolon between the function signature and the function body. Additionally, there is a stray string ("Hello on the screen") that is not being used in any statement or function, possibly indicating a missing alert or console log function.
