It's only less noisy because of the simplistic nature of the example. In real world code, `one`, `two` and `three` and probably a chunk of code put together in a single line and it's difficult to find out what the hell they are doing. Concat together a few of these and that's a recipe for disaster. Less experienced engineers would add a comment at the top of the pipe chain explaining what's going on. More experienced engineers would divide and conquer and use temporary named variables (render commets useless).
