JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables Combining Strings

‘Welcome’ + ‘to’ + ‘treehouse’ is contradicting what Dave says

In the video, Dave says that adding two strings won’t automatically put a space in-between yet, next he shows:

‘Welcome’ + ‘to’ + ‘treehouse’ = Welcome to treehouse

That contradicts what he just said. It should equal:

‘Welcometotreehouse’ right?

This was probably just a mistake, but please tell me if it isn’t.

If you write

/cc Chris Upjohn

Does that notify you?

The /cc doesn't matter, mentioning mean when using @ does notify I and any other mentioned user (including you) via notifications.
