> Until, of course you have to actually maintain this and has to chase down 3 or 4 levels of functions deep what is it that the code is actually doing.

The art is to chain your short functions like a paragraph, not to nest them a mile deep, where the "shortness" is purely an illusion and the outer ones are doing tons of things by calling the inner ones.

That's a lot harder, though.

But it fits much better with the spirit of "don't have a lot of args for your functions" - if you're making deeply nested calls, you're gonna have to pass all the arguments the inner ones need through the outer ones. Or else do something to obfuscate how much you're passing around (global deps/state, crazy amounts of deep DI, etc...) which doesn't make testing any easier.
