22,248 Pointsreturn vs. echo in method
In challenge of 5, wouldn't you want to echo the statement? Doesn't a 'return' just save the statement as a variable? I get why you return a value to work with, but why would you return a sentence?

You can assign it to a variable, but you can also just echo it, echo $bass->getInfo(), use it in a conditional, if( $bass->getInfo() == "some string") { //do something }, pass it to a function, someFunction($bass->getInfo()), etc. The point is, at least in this example, the class is more reusable since it returns a value rather than just echoing something from within the class.
