Answer 1

That's because window.names is not defined. By the way, a lot of semicolons in the code are missing.

Answer 2

You should be careful, because variables defined locally in a function won't be available outside of it.

Answer 3

It doesnt matter whether i use semicolon or not in javascript. But i have no idea why it doesnt work where as i used window.names to call variable names inside another function.

Answer 4

Yes, but the problem is that you declared the variable inside a function. You should do it outside it. Same with verbs, nouns and the rest of it.

Answer 5
