Apparently it's 2/3 times faster than the Go version.
Whatever one think, the fact that there's 4 vibe coded compilers, 2 of those with 100% coverage of the official one and all being much faster than the Go version should be a wake up call for the TypeScript team.
Despite the resources and having a huge team of people that are clearly good at programming languages and compilers, something is definitely not working as it should there if vibecoders can get much faster fully compliant compilers.
