FP-TS Async-Example (read file/parse yaml asynchronously)

Learning FP-TS and trying to work with some real world examples.

This project is my experimentation with FP-TS asychronous Task. I was able to successfully work with a synchronous version of this project here: https://github.com/anotherhale/fp-ts_sync-example. I was able to resolve the issues with the initial async code thanks to @MnZrK from this SO post: https://stackoverflow.com/questions/57316857/resolved-how-to-chain-dependent-taskeither-operations-in-fp-ts.

npm run build

npm run start

Resulting application output:
