Go

Static typing, zero values, explicit conversion.

if / for / switch / defer — minimal by design.

Multi-return, variadic, methods.

Go's two everyday containers — gotchas and idioms.

Composition over inheritance — the Go way.

Structural typing, the empty interface, and io.Reader.

go.mod, internal/, exported names, the toolchain.

Explicit failure: error values, wrapping, errors.Is / errors.As.

Concurrency the Go way: cheap goroutines, typed pipes, select.
