Figment is a collection of functional programming helpers. This is my personal collection of utilities and is not intended to be comprehensive.
The library is built in TypeScript and is manually curried to make the final parameter to functions (the data parameter) a separate callback to aid in composibility. For example, here is the signature of map from lodash:
type map = <T, U>(fn: (item: T) => U, items: T[]) => U[]
const increment = a => a + 1
const result = map(increment, [1, 2, 3])And here is the signature this library uses:
type map = <T, U>(fn: (item: T) => U) => (items: T[]) => U[]
const increment = a => a + 1
const incrementList = map(increment)
const result = incrementList([1, 2, 3])yarn add @tdreyno/figmentnpm install --save @tdreyno/figmentfp-ts is a popular TypeScript library which implements functional concepts.
