Well, the context is Node.js, and I would definitely use promises over streams for what’s described in the article (albeit more directly). Node streams are complicated with a lot of historical baggage, and massive overkill for waiting on a single value produced by another operation.

The point was that it's not a single value, it's a stream of values (e.g the compileServer can start working with partial results of the compileBrowser function). Of course if it was a single value, promises are fine. A simpler and more modern alternative would be async iterators/generators[0].

But it wasn’t. Despite the author calling it a channel, it only supports one value.
