My step-by-step to learn a new programming language

I'm never learning a new language by reading topics on documentation, I always look for a problem I already solved in the past and try to replicate the behavior.

Here are the steps I followed to learn Dart and Golang

• Identify the problem I want to solve
  I want to get a full address with a given zip code
• Put on the table the flow I need to get this job done
  I need to expose a function called GetAddress(zipCode string) and perform a search on multiple zip code search providers to get the address. So I'll probably need to do a for loop, HTTP request and handle some async stuff
• Build a first version
  Focus only on making things work, at this time we'll have a code with "accent" from past languages we worked with. The "accent" is when you program in Python and start programming in Javascript and name your functions like get_address() instead getAddress()
• Afterward, look for the standard of the language you want to learn
  Just get the things you did and search for a pattern it should be to remove that accent

At the end of your journey, a new open-source project might be born
