> for the longest time all I kept hearing is how incredibly fast things written js are… I am sure no-one ever claimed that things (properly) written in JS are as fast as things (properly) written in C, Go, or Rust, and running in a native environment. JS on the server may have been faster than php or python, due to the non-blocking nature of the event loop; but even that may not be the case anymore. Generally, the pitch has been that js is "fast enough" for most tasks.
