Question

question: 1
why do we write functions?

• to make our code easier to understand by giving a readable name to a group of instructions
• to avoid writing repeated code
• to make our code reusable
• all of the above

question: 2
consider the following function:

function rolldice() {
let roll1 = randomizer.nextint(1, 6);
let roll2 = randomizer.nextint(1, 6);
console.log(\you rolled \ + roll1 + \ and \ + roll2);
}

what would be the correct way to call this function?

• rolldice;
• rolldice();
• function rolldice;
• function rolldice();

Explanation:

Question 1

• Naming a group of instructions with a function makes code understandable.
• Functions help avoid repeating code (DRY principle).
• Functions can be called multiple times, making code reusable. So all options are correct.

• To call a function in JavaScript, we use the function name followed by parentheses ().
• rollDice; just references the function, not calls it.
• function rollDice; and function rollDice(); are incorrect syntax for calling (they are for declaration or incorrect usage).
• rollDice(); is the correct way to invoke the function.

Answer:

D. All of the above
