Functional syntax for common array tasks.

ArrayShorthands

ArrayShorthands provides methods for filtering on arrays using direct invocation. The Ash class instances can be initialized using the same parameters as Array class instances, and proxy all Array member functions such as .filter, .forEach, map etc.

Install

npm install array-shorthands

Usage

import { Ash } from "array-shorthands"

// intialization takes same parameters as an array
let arr = new Ash({ a:1, b:2 }, { a:2, b:3 }, { a:3, b: 4}, { a:1, b:3 })

// filter by parameter, as key=val
arr("a=2") // returns [{ a:2, b:3 }]

// filter through fn directly
arr(a => a.b % 2 == 0) // returns [{ a:1, b:2 }, { a:3, b: 4}]

// "and" chain filters with , operator
arr("a=1,b=3") // returns [{ a:1, b:3 }]
arr("a=3,b=3") // returns []

// "or" chain filters with ; operator
arr("b=2;b=3,a=1") // returns [{ a:1, b:2 }, { a:1, b:3 }]
arr("a=1;a=2,b=2;b=3") //returns [{ a:1, b:2 }, { a:2, b:3 }, { a:1, b:3 }]
