changelog

• replaces ijavascript kernel with a fork that includes a compiler step and promise resolution
• removes typescript compiler step as this is now built-in in the kernel
• tests/docs will follow in a separate PR

kernel changes:

• https://github.com/n-riesco/ijavascript/compare/master...e2b-dev:ijavascript:master
• https://github.com/n-riesco/nel/compare/master...e2b-dev:nel:master

one note: currently Node will issue a warning to stderr when trying to import ESM module - we can disable that in the kernel.

Examples

snippet:

import got from "got"

before:

Execution {
  results: [],
  logs: {
    stdout: [],
    stderr: [],
  },
  error: ExecutionError {
    name: "SyntaxError",
