@ariadne TBH, last week I actually suggested rewriting a system to use TypeScript/Node.js for performance reasons. V8's optimizer is quite good, and I've found it comparable to Java once it warms up.
To be fair, this was not at all the case when webOS was around.
Rust would be faster, but I don't think that'd make enough of an impact on the required compute resources to justify the higher development costs.
