HOW

ゴール: verify isStream detects Node.js stream instances and differentiate readable writable duplex and transform streams
パッケージ: is-stream 2.0.1
シンボル: isStream

isStream returns true for Node.js Stream instances and objects with a pipe method, and false for primitives and plain objects
isStream.readable returns true for readable streams including Readable, Duplex, and Transform, and false for purely Writable streams or non-streams
isStream.writable returns true for writable streams including Writable, Duplex, and Transform, and false for purely Readable streams or non-streams
isStream.duplex returns true for streams that are both readable and writable such as Duplex and Transform, and false for purely Readable or Writable streams
isStream.transform returns true for Transform and PassThrough streams, and false for standard Duplex, Readable, or Writable streams
