how can I know when the parenthesis are necessary to invoke a method?

Length is actually a property, not a method. For properties, you don't need to add parenthesis. Think of properties like variables. They hold Information about the object, like its length, for instance. Methods are like functions. They're actions that you can call on an object.

13,582 PointsThanks Kevin. I got confused because it was applied in the video for methods. It makes sense now. I appreciate it.

32,834 PointsNo problem. I actually had a hard time deciphering the difference between the two up until pretty recently. It can be pretty confusing.
