simple ts runner (for coding challenge alike)

the convention:

put the folder of the typescript module inside the src e.g in this case "day1"

mkdir src/day1
touch src/day1/index.ts

inside you could put the operation on top level, or you must put the default main function to be executed

// index.ts

export default function main() {
  console.log('hello world');
}

just execute it

yarn exe day1

and, voila!
