What do I've to learn to make an app that has to do with maps

Hi, I am starting to learn JavaScript.

My objetive is to make a website and an app who help me find where are the ATM of my country.

People can help to add new ATM, and the main function of the app is to locate the nearest ATM, and guide you arrive to it like google map does.

Which is the roadmap should I take?

the whole freeCodeCamp curriculum should give you enough of a basis that you would be able to orient yourself after in how to do this app

I concur, but you absolutely cannot skip the D3 part of the curriculum, especially the choropleth, since that is only explicit map making part of the curriculum. There’s also some bits in the advanced javascript that would be very helpful, especially the stuff on trees and paths.
