JavaScript Object-Oriented JavaScript Object Basics Dot Notation & Bracket Notation

Property keys can have spaces inside them?

In this lesson it is said that 'bracket notation allows us to access or create properties that have spaces inside the property key'. This goes against what I learnt so far, I thought that property keys should follow the same rules for naming variables, which means no spaces inside!

Can someone give me an explanation?

That's one of the differences between dot and bracket notation. The video encourages you to think of bracket notation as the style that's used less frequently as it's more difficult to read but has more flexibility. It's totally up to you which style you prefer but it's good to know both. :-)
