How to determine your skill?

Question

JavaScript

I have been working with angular 1 for about two years (the first year is not very active), recently with angular 2 and node. Of these, 6 months. at the office.
During this time, I worked on two medium-large, or maybe even large, projects on angular 1 and one on angular 2. Now I took a freelance project on a node and I’m not bad at it, at least they don’t complain. But I want to go to the office, it’s easier to raise the skill there, but how to determine what I stand now? What salary to ask? It seems that it is no longer junior, but here I am, or I reach middle xs.
PS I have no IT education, I taught everything myself. English at a medium-weak level.

Answer 1

How do you understand junior, middle (developer), senior, and is there a fundamental difference between these concepts in the web, embedding, game development and other programming?

Answer 2

Go to interviews and it will become clear. Take it to the max.
