transform-iterable

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

Install

$ npm install transform-iterable --save

Usage

const TransformIterable = require('transform-iterable')

const iterable = new TransformIterable([4, 2, 7, 8]) // (4 2 7 8)
    .map(e => 3 * e) // (12 6 21 24)
    .filter(e => e % 4 !== 1) // (12 6 24)
    .dropWhile(e => e % 12 === 0) // (6 24)
    .takeWhile(e => e <= 12) // (6)



// converting to array:
[...iterable] // [6]

// 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: undefined, done: true}
