Go's design is certainly influenced by the languages that came before it, but because its designers deliberately decided to remove features, not add them. These are legends in the industry after all, so it's not like they weren't aware of these things. It's a testament of skill to produce a language that is simple, user friendly and powerful at the same time, and they made the right tradeoffs to do this successfully IMO.

On the other hand, the list of warts and gotchas in JS land is neverending. The fact we're likely stuck with it forever because of the mountain of software that depends on it is deeply unsettling.
