Except Nim compiles to C and JS, no official WASM yet (though you can Emscriptenize the C output). Nim has macros, generics, inheritance, exceptions, deterministic GC, and more. Otherwise, yeah, exactly the same.

Go and Nim are as different as it gets in programming language design. Nim is kitchen-sink type language, while Go builds on a small set of well-defined features. It's the difference between Scheme and Common Lisp, or JavaScript and Python - the look&feel of programming in Nim is unlike Go in almost all respects, aside from perhaps quick compilation.

Go is nowhere near as expressive/high-level as Nim or Python.

The learning curve is significantly steeper.

It is literally un-go. Great support for meta programming and generics, and actual non-foot gun error handling

It's way nicer than Go (features and syntax) tooling and libs are not as developed obviously.

Except Nim doesn't make you copy/paste constantly.
