oof!
oof is a tiny TypeScript library for functional programming utilities with type safety. When learning functional paradigm with JavaScript, you may feel some despair of typing pipe (or go) correctly.

// you only type once
const foo = oof((x: string) => x.length)
.compose(num => num === 42)
.compose(isTruthUnveiled => isTruthUnveiled ? () => console.log("I'm die. Thank you forever.") : () => {})
// you can call this directly
foo() // foo(x: string): () => void
// want to proceed more?
const bar = foo.compose()Why?
// You're currently writing a nice composed function...
pipe(
(value: string) => returnsSomeNiceComplexType(),
// Parameter 'iWantNoImplicitAnyBeTrue' implicitly has an 'any' type (7006)
(iWantNoImplicitAnyBeTrue) => butYouCantBecauseAboveTypeIsHell(),
)
// This is also verbose
// since most of the time you start with inner things
const result = pipe<[Do, I, Have, To, Declare, These, Always, QuestionMark]>(
