It's chaining without having to vary the return of each function. In JS you cannot call 3.myMethod(), but you could with 3 |> myMethod

[cyco130]

It requires parentheses `(3).myMethod()` but you can by monkey patching the Number prototype. Very bad idea, but you absolutely can.

[senfiaj]

You can just add extra dot: `3..myMethod()`.

Not only that

In chaining, methods all have to be part of the same class.

In C++ we had this stuff ages ago, it’s called abusing streaming operators LMAO
