I did C++ and some C~Sharp in college (UK college) and the lecturer really confused us when we start doing JavaScript, this helps, and thank you.

May I ask you a question, after assigning a property(firstName) to the empty arr2, why arr2.length is 0 instead of 1?

Hi and thanks for the great explanation in this tutorial. I'd like to know when do we use objects in a project or in a website? I have no clue when to apply some of the things that I've learnt in JS. Could you give some real examples when would we use objects? This will really help and give me a better idea about objects. Thanks again for your support.

I'm confused, why do many of these instructional and educational videos distinguish between primitive data types (numbers, strings, boolean) and objects, BUT then give examples where those primitive data values are examples of an object?

Did this video play weird for anyone else?
