I wouldn't say that it has a very strong Go fondation because it seems that Odin doesn't have an equivalent to God's channels..
My understanding is that Odin does not plan to ever attempt to put concurrency nor channels into the language. It looks like that some type of workaround, if it ever happens, will have to be implemented by a 3rd party library.
It should be added, Vlang (the other Go alternative mentioned) because it was designed for various memory management options (both automatic and manual), does do concurrency and channels (https://github.com/vlang/v/blob/master/doc/docs.md#concurren...). Vlang aims to be more general purpose versus more specific.

We are planning on adding channels to the core library but we have not added them yet since there are quite a few different forms (SPSC, SPMC, MPSC, MPMC).
One thing that I would like to bring up is that Odin differs from Go in that it does not have `go`routines (green threads). These require automatic memory management and a huge runtime to make them possible. And you cannot easily add them after the fact to a language either without huge issues. Channels are very basic things but the thing that makes Go's concurrency powerful are the `go`routines, not the channels.
