What do you need to learn to create a browser-based online game?

Question

Game development

Hello. In the future I want to create an online browser game in 2D, top view. Can you please tell me what to study?

Answer 1

Nobody knows what you want to use - there are many ways to do the same thing.
Nobody knows what you already know. If nothing, then you need to learn everything.
It's too early to ask such a question.
First learn to do something simpler, and when you can ask the right question, then ask.
The right question hides about half of the answer. You don't have it, and the answers won't help you. Because there are MANY options.
