Create a stream that emits events from multiple other streams
Resolve the path of a module like `require.resolve()` but from a given path
ECMAScript AST recursive visitor
deterministic `JSON.stringify()` - a faster version of substack's json-stable-strigify without jsonify

Light ECMAScript (JavaScript) Value Notation - human written, concise, typed, flexible
Promisifies all the selected functions in an object
deterministic JSON.stringify() with custom sorting to get deterministic hashes from stringified results, with no public domain dependencies
Buffers events from a stream until you are ready to handle them.
Merge multiple streams into one stream in sequence or parallel.
