> The main advantage of Go is that it makes it easier to parallelize your code thanks to goroutines and channels

Well, that and Go is not bounded by a VM (jit or no), and will simply be faster than JavaScript, given the exact same logic. Don't discount the cost of running on a VM, and all of the abstractions which are thrown on top of plain JavaScript to help manage the callback complexity.

Given enough money, a JIT can be made arbitrarily fast, it seems (e.g. - JVM, LLVM bitcode interpreter)

Given time, don't assume any particular language implementation will always be faster. Go might only run faster than Javascript on the odd years, depending on corporate budgets for compiler / VM tuning the previous year.

The JVM has received a lot of money and attention over the years, yet still falls quite short of its direct compiled competitors in almost any benchmark. The threshold for "enough" when it comes to improving a JIT is still arbitrarily high.
