Before I had a reference book of the language. Also I would program always in the same language before stack overflow. Now I switch between so many languages.

Before I had a reference book of the language. Also I would program always in the same language before stack overflow. Now I switch between so many languages. But still use references. But now it's easier in Dash.app I have references to most of the languages, API, libraries I use. This way if I want to know how to make if then else syntax work in Go or Javascript or Python I can look it up super fast. Same for Libraries and API's. Now language idioms is something you need to keep on top off. These are better to remember so you can implement it.
