Go Under the Hood: Memory, Concurrency, and Mental Models Most Developers Get Wrong

#beginners #go #tutorial #programming

Go is often described as a “simple” language.

And syntactically, it is.

But many production bugs in Go don’t come from complex code — they come from incorrect mental models about how Go actually works under the hood.

This guide is a collection of practical explanations about Go’s execution, memory, and concurrency model — not as a tutorial, but as a way to fix the most common wrong assumptions developers make.
