Doesn't go also make it relatively easy to write parallel code?
Go's implementation of these things is nice, neat, and all included out of the box though which is nice.
In general you can make parallelism easy, or efficient, rarely both, at least not in a way that can solve problems generally.
edit: I should add Go does also come with a data-race detection tool which can be very useful. Not sure any other language includes that out of the box!
Still not quite as tightly integrated as Go though.

Rust's compiler does it by default, at compile time. ;-) Go's race detector is never wrong, but it may omit things. On the other hand, Rust's compiler is also neither wrong nor does it omit things, except under one circumstance: someone, somewhere, wrote `unsafe` code and committed a bug inside that block.
ThreadSanitizer is also a thing: https://clang.llvm.org/docs/ThreadSanitizer.html
