Package Exports

orb-functions

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (orb-functions) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

<script src="https://cdn.jsdelivr.net/npm/orb-functions@1.0.0/dist/index.js"></script>

Node Installation

npm install orb-functions

self

It returns the first input argument it is called with.

// Example
const input = [1, 2, 3]
const toObject = ({items, key: kfn = self, value: vfn = self}) =>
  items.reduce((c /** container */, v) => (c[kfn(v)] = vfn(v), c), {})

toObject({items: input})
// Output {1:1, 2:2, 3:3}

toObject({items: input, value: Math.square})
// Output {1:1, 2:4, 3:6}

constant

It is useful in the situations which require a function to return a fixed value.

// Example
const input = 'suhm'
const cfn = constant(input)
cfn()
// Output 'suhm'
