Adobe Exam AD0-E213 Topic 5 Question 55 Discussion

[All AD0-E213 Questions]

When may the JavaScript exception 'TypeError: "x" is not a function' occur?

Show Suggested Answer Hide Answer
Suggested Answer: C

The JavaScript exception 'TypeError: 'x' is not a function' occurs when the type of the value returned by function V does not match its declared type. For example, if a function is declared to return an integer but returns a string instead, this exception will occur. This can happen when incorrect data types are used or when the function is called with the wrong number of arguments.

I agree with Veronica. If the function is called before it is defined, it can lead to that error.

Ah, the perils of dynamic typing. I bet the correct answer is B - calling a function before it's defined.

This is a common error I've encountered when I forget to add parentheses after calling a function. Rookie mistake!

I think the JavaScript exception may occur when function V is called after it is defined.
