NEW QUESTION # 29
Refer to the code below:

console.log('flag');
}
const anotherFlag = () => {
console.log('another flag');
}
anotherFlag();
What is result of the code block?

A. An error is thrown.
B. The console logs only 'flag'.
C. The console logs 'flag' and 'another flag'.
D. The console logs 'flag' and then an error is thrown.

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract JavaScript Knowledge:
Key points:
Function declarations are hoisted (their definitions are available before the line where they appear).
Function expressions assigned to const or let are not hoisted as callable functions, but here anotherFlag is only used after it is defined.
Step-by-step:
flag(); at the top:
flag is a function declaration defined later; due to hoisting, it is available.
It logs 'flag'.
The declaration:
function flag() {
console.log('flag');
}
is already in effect (hoisted before execution).
const anotherFlag = () => { console.log('another flag'); } defines anotherFlag as an arrow function.
anotherFlag(); is called after its definition; this is valid and logs 'another flag'.
No errors occur. The console output is:
flag
another flag
So option D is correct.
Concepts: function hoisting, difference between function declarations and function expressions, execution order.
