Batch processing support for node.js

[dilipkumar2k6]

I am using sloc with my node.js code. Currently my code takes one file content at a time.

const {total, source} = sloc(content, extension);

How can I support batch processing to make it faster? I have requirement to process 1000+ files at a time. Batching will help. I am looking for something as below.

const [{total, source}] = sloc([content], [extension]);
