I'd like to become a Solidity developer, my main goal is to have the skills needed to work for a project. I don't know what's the minimum amount of knowledge needed and what could be an optimal path.

For example:

learn Javascript, node.js, solidity, at least one framework like Hardhat / Truffle

what else?

I am already working as a Java dev. I would like to go straight for the main goal. For example I would leave minor parts for later
