functor-arraylike-iterable v0.1.3

functor-arraylike-iterable

functor-arraylike-iterable exports a class that builds iterables that provide map method.

Install

$ npm install functor-arraylike-iterable --save

Usage

const FunctorIterable = require('functor-arraylike-iterable')

const iterable = new FunctorIterable([4, 2, 7, 8]) // (4 2 7 8)
    .map(e => 3 * e) // (12 6 21 24)
    .map(e => e / 2) // (6 3 10.5 12)



// converting to array:
[...iterable] // [6, 3, 10.5, 12]

// traversing values:
for (const val of iterable) {
    // ...
}

// creating an iterator that traverses the values
let iterator = iterable[Symbol.iterator]()
iterator.next() // {value: 6, done: false}
iterator.next() // {value: 3, done: false}
iterator.next() // {value: 10.5, done: false}
iterator.next() // {value: 12, done: false}
iterator.next() // {value: undefined, done: true}
