What is the difference between util.pump(streamA, streamB) and streamA.pipe(streamB)?

Question

The source code looks very similar: pump, pipe. Why would I use one instead of the other? Is one simply a better version of the other?

Answer 1

It's worth to say that pump is only necessary for Node.js 8.x or earlier, as for Node.js 10.x or later version, pipeline is introduced to replace for pump. This is a module method to pipe between streams forwarding errors and properly cleaning up and provide a callback when the pipeline is complete.
