Portable, lightweight JavaScript method extensions, minus the monkeypatching.
As a managed local dependency (do this): npm install --save bind-infix
As a managed local development dependency (or this): npm install --save-dev bind-infix
As an extraneous local dependency (preferably not this): npm install bind-infix
As a global dependency (and especially not this): npm install -g bind-infix
// 1. Import the infix function
import infix from 'bind-infix'
// 2. Define a prefix-call implementation of a generally useful method,
// such as flatMap
const prefixflatMap = (array, mappingFunction) =>
array.reduce(
(partialResult, nextElement) =>
[...partialResult, ...mappingFunction(nextElement)],
[]
)
// 3. Create an infix-call implementation of the prefix-call function
// using the infix function
const flatMap = infix(prefixflatMap)
// 4. Call your new function using the bind operator
const chars = ['Hello,', ' ', 'world!']::flatMap(string => [...string])
// chars = ['H', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd', '!']This module has no transitive, peer, or development dependencies. Node and npm are the only practical requirements for use. This module can also be easily recreated in a couple of lines of code (even only one) in virtually any JavaScript environment.
It is highly recommended that code calling functions enhanced by the infix function be written for a native or transpiled JavaScript environment with support for the :: (bind) operator. This module really only provides syntactic benefits, which rely entirely on the :: operator to be effective. The babel-preset-stage-0 module provides support for the :: operator when using babel as a transpiler.
