You’ll get some questions about object properties, such as whether objects are passed by value or reference. The answer to that question is that all objects pass by reference. Any changes to an object’s reference changes the object itself. Finally, be prepared to address specific examples. You might get asked about whether the object that
document.getElementsByTagName() returns is an array. (Nope. That’s an HTML collection.) You won’t know what the examples will be, so spend some time each night before the interviews to study a variety of sample questions to prepare for the interview.
