What courses to do to become Aras developer?

My company is going to be deploying Aras Innovator soon, in a few months.

We may have an in-house developer for this and I am very interested in this role.

I know basics of JavaScript, made a few websites using React, HTML, and CSS.

I was wondering what courses should I be doing to prepare for becoming an Aras developer.

Does know advance concepts of JavaScript help?

Did anyone do  the Developer courses provided by Aras? 

Basically, what programming concepts, courses, documentations, and other resources  will help me step into this role?

Thanks!
