| Block scopes are what you get when you use if statements. | |
| Global scopes can be slow, because each time a function executes, it causes a temporary calling scope to be created. JavaScript searchers for the first item in the scope chain, and if it doesn't find the variable, it swells up the chain until it hits the global object. | |
