Array2D

Array2D is an auxiliary tool to create, manage and manipulate 2d arrays. I made this component to help me develop board game prototypes. If you want to use this component, please! If you want to modify or expand this component, you are welcome to do so. See notes in contribution.

Installation

$ npm i Array2D --save

Usage

import Array2D from 'array-2d-js'

export default class Map extends Array2D {
  constructor (width, height) {
    super(width, height)
  }
}

or

import Array2D from 'array-2d-js'

const array2D = new Array2D(10, 10)

or

const Array2D = require("array-2d-js")

const array2D = new Array2D(10, 10)
