Typescript (deno), Python and Go. Tbh the goal is really not to compete with AWS Lambda on performance as they use microvm with hot http servers, but to show that it's not order of magnitudes slower.
But yeah if you're showing your comparable or same ballpark the criteria is less crucial. Was mainly just adding addtional data. Good luck on the project. A light framework like this for essentially scripts locally without kube or heavy docker is nice.
