Isn’t the entire language designed explicitly to prevent programmers from building their own sophisticated abstractions that could confuse other programmers who don’t understand that other persons code… as I understand it, if you can read go and understand basic programming you should be competent with go, and if you know your algorithms you should be proficient.
I hated old Java but the modern language isn’t as bad now some people have added some better syntax shortcuts the libraries are nearly twenty years more polished, and the IDE can nearly half write my code for me so the boilerplate and mind numbing aspect isn’t so bad… I loathe go because using it feels like programming with my hands tied behind my back trying on a keyboard with sandpaper keycaps, despite that, I didn’t bother “learning” go, I could just read it based on my Python/C/Basic/Java/C# experience instead of needing any extra learning.
