Salesforce Exam Javascript Developer I Topic 4 Question 97 Discussion

Refer to the code snippet:

Function getAvailabilityMessage(item) {

If (getAvailability(item)){

Var msg =''Username available'';

}

Return msg;

}

A developer writes this code to return a message to user attempting to register a new

username. If the username is available, variable.

What is the return value of msg hen getAvailabilityMessage (''newUserName'' ) is

executed and getAvailability(''newUserName'') returns false?
