You say that to invoke a method is necessary to add () But when you used the method length you didn't use it.

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

Hey Jorge,

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.

Thanks Kevin. I got confused because it was applied in the video for methods. It makes sense now. I appreciate it.

No problem. I actually had a hard time deciphering the difference between the two up until pretty recently. It can be pretty confusing.
