It'd be in a non-native language, like C#.
JavaScript is faster than you think. Miles ahead of Python, Ruby, Perl, PHP. Not too different than C#/Java (especially if you consider 2x to be effectively the same) [1].
True; C# is the most obvious choice for Teams.

I'd be very surprised.

Depends on "miles" - I think it is within the same order of magnitude as all of those. If it's far off from being in the same order of magnitude of those, I'd be very surprised.

I don't think so, not for idiomatic usages anyway. Java and C# are pretty damn fast! ISTR that Java/C#/Go are in a different order of magnitude from JS, Python, PHP, etc.

And Java/C# is nowhere even close to an order of magnitude faster than JS.

The better showcase would be complex application code where JS cannot keep up with .NET or JVM no matter how much you optimize V8 due to dynamic typing and even simplest operations like property access needing inline caching and guards.

déjà vu all over again
(Or would C# aot and GraalVM be more to the point?)
