functor-filter-arraylike-iterable

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

Install

$ npm install functor-filter-arraylike-iterable --save

Usage

const FunctorFilterArrayLikeIterable = require('functor-filter-arraylike-iterable')

const iterable = new FunctorFilterArrayLikeIterable([4, 2, 7, 8]) // (4 2 7 8)
    .map(e => 3 * e) // (12 6 21 24)
    .filter(e => e % 4 !== 1) // (12 6 24)



// converting to array:
[...iterable] // [12, 6, 24]

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

// creating an iterator that traverses the values
let iterator = iterable[Symbol.iterator]()
iterator.next() // {value: 12, done: false}
iterator.next() // {value: 6, done: false}
iterator.next() // {value: 24, done: false}
iterator.next() // {value: undefined, done: true}
