  • Transpiling to JavaScript forces languages to inherit JavaScript's quirks, impacting performance.
  • This is problematic for languages like C++ that have different properties.

  • JavaScript's number representation, where every number is internally a float, poses challenges for transpiled languages.
  • This necessitates boxing types, adding overhead for languages that don't require it.
