pipe2.ts

const { value: h } = new Pipe("balls")
.$(x => x.toUpperCase())          // string -> string
.$(x => x.length)                 // string -> number
.$(x => (console.log(x), x > 3))  // number -> boolean
// console log and return a value, arrow function implicitly returns the last expression

console.log(h) // boolean
