My interpretation of the title was that it was going to discuss how the Dis VM[1] compared to popular JS VMs, but I was sorely disappointed.
(Inferno, for those not aware of it, is a rather obscure successor to the almost-as-obsure Plan 9 From Bell Labs. Plan 9, in turn, was supposed to be the replacement for UNIX. Unfortunately it failed because UNIX was "an existing codebase that is just good enough"[2]; its main lasting contribution was the invention of UTF-8[3].)
