How to Set up an Ethereum Dev Environment

So you want to be an Ethereum developer! Congrats, much treasure awaits you. Developing Ethereum dapps benefits from having a well-crafted development environment. This can often be daunting to beginners, so I'm giving you my favorite dev environment to help get you started.

Once your code fortress is constructed, you'll be able to

Compile smart contracts written in Solidity

	vedo che c'è parecchia confusione su typescript, a partire da cosa sia.
	cercherò di fare chiarezza su cosa sia, a cosa serva e quali sono pro/contra di utilizzarlo:
	typescript, come flow, nasce come type system INCREMENTALE per javascript, il che significa aggiungere dei metadati nel codice che possano essere consumati da qualcuno (tsc per ts e babel via plugin per flow) in modo da rendere fortemente tipato un linguaggio che lo è solo debolmente, senza però obbligare lo sviluppatore a tipare tutta la codebase prima di utilizzarlo ma favorendo anche un ingresso graduale in progetti pre-esistenti.

	cosa è un tipo? semplicissimo:

	- "stringa" -> string
	- 42 -> number

	un po' meno semplice:
