questions about learning Data Structures and Algorithms in a specific language (noob question)

just some background info – I have a basic understanding of python after self-teaching myself for a couple of weeks. I am a complete noobie and haven’t created a project yet.

The next step for me is trying to learn DS and A. However, one of the resources that Im looking at to learn DS and A is in JavaScript. After looking at what others had to say, most recommend that it doesn’t matter what programming language the DS and A resource is in because the goal is to understand the concept. However, to what extent is this true?

Would I be able to easily translate and implement what I’ve learned from a JavaScript DS and A course to a project in Python? Or should I just find a resource in Python?

Also, just a more general question – how is learning data structures and algorithms useful and utilized in python or any other language? Would someone be able to start creating projects without an understanding of data structures and algorithms and just an understanding of a programming language?

Sorry for the many questions, I am just trying to best prepare myself. I would really appreciate any replies
