@TheNeuralBit @trxcllnt could one of you review?

Ups. Yes, I fixed the reference.

the https://arrow.apache.org/docs/js/ documentation is still much less, incomplete if comparing to other implementations, Especially can someone explain how to write arrow files? before I can start play with apache-arrow JS package, where is a place can I download some sample arrow files? how can I convert my existing dataset (some csv, json, and avro files) to arrow format?
https://arrow.apache.org/docs/js/classes/recordbatchwriter.html (where are howto using RecordBatchWriter, RecordBatchFileWriter, & RecordBatchStreamWriter)

Wonder is this Implementation Status kept current? Look at other releases have 1.0.0 and 1.0.1 but on NPM the apache-arrow is still left at 0.17
