Is there any difference between fs.ReadStream and fs.createReadStream in Node.js?

Question

In fs module in Node.js, is there any difference between fs.ReadStream and fs.createReadStream? As far as I know, both take filename and then create stream object...right?

Answer 1

No

https://github.com/nodejs/node/blob/1124de2d76ad7118267d91a08485aa928a5f0865/lib/fs.js#L1711

fs.createReadStream = function(path, options) {
  return new ReadStream(path, options);
};

Fine print: YES. fs.createReadStream costs you 1 extra wrapper function call
