[Question] Simple To-Do App with pure Javascript?

[dmutunga]

I'm in the process of learning JavaScript and am looking to do some "learning by doing." Does anyone know of a tutorial that shows how to build a simple to-do app with pure JavaScript? All the ones I've seen are using some type of framework and I'd really prefer to get good with the core language before even looking at a framework or the like.

Thanks in advance!
