Is this the correct usage of extending a class?


I have made a mini dom manipulation library in codepen to test what I learned about js classes however after looking at the code it feels like a lot of boilerplate and wondered whether there is a better way to do what i'm doing.


Any help much appreciated, Matt

If you just wanted to practice class structures it looks like you did a good job. Otherwise, I'm not quite sure what you're after. If I wanted functionality like this, I'd just load jQuery.

One issue caught my eye: there's no "getElementsByID" (plural) method. Since ID's must be unique, there's only a "getElementById" method that returns a single element.
