question: 13
what would be the correct way to name a function that tells us the day of the week?

• function dayofweek() {

...
}

• function day_of_week() {

...
}

• function dayofweek() {

...
}

• function dayofweek() {

...
}

Explanation:

In JavaScript (the context of these function definitions), the correct naming convention for a function that is in camelCase (a common and standard way to name functions in JavaScript) would be dayOfWeek(). The first option dayofweek() is all lowercase without proper separation, the second day_of_week() is snake_case (more common in Python for functions but not standard in JavaScript for function names), and the third DayOfWeek() starts with a capital letter which is more for constructor functions (like classes) in JavaScript. So the function dayOfWeek() follows the camelCase convention where the first word is lowercase and subsequent words start with a capital letter, making it the appropriate way to name this function.

Answer:

D. function dayOfWeek() {
...
}
