I think they a lot of developers that didn't start with front-end work find Javascript disgusting, maybe this team is in that group.
I am not a Javascript fanboy, but the syntax of GoLang is not better either.

Javascript's dynamic typing, extensive use of callbacks, its approach to OO, inconsistent braces and semicolons, etc are all felt by a lot of people to be messy.
For me lack of something like gofmt and a compile time errors also greatly detract.
