Noticed this bit of code in lib/stream.js on the master branch:

const version = process.version.substr(1).split('.');
if (version[0] === 0 && version[1] < 12) {
  Stream._uint8ArrayToBuffer = Buffer;
} else {
  ...
  1. Since the code internal in node can only ever be the version that it is, it seems odd to be checking the version in this way.
  2. It looks like it's checking for node 0.x < 0.12??
  3. Splitting a string returns an array of strings, so version[0] === 0 would always return false even in node 0.11 and before.

I think this can be removed?

  • Version: 12.12.0
  • Platform: All
  • Subsystem: stream

I think it was added for readable-stream but yeah it seems broken and readable-stream now requires Node.js >= 6.

`String.prototype.split()` returns an array of strings so the branch is
never taken.
