two-d-array

A simple utility to create a 2D array with specified dimensions and a default value.

Installation

Install the package using npm:

npm install rootedbox-two-d-array

or yarn

yarn add rootedbox-two-d-array

Usage

Require the package in your JavaScript or Node.js project:

const twoDArray = require('yourusername-two-d-array');

Then, use the twoDArray function to create a new 2D array with the desired dimensions and default value:

const rows = 3;
const cols = 4;
const defaultValue = 0;

const myArray = twoDArray(rows, cols, defaultValue);

console.log(myArray);
// Output:
// [
//   [0, 0, 0, 0],
//   [0, 0, 0, 0],
//   [0, 0, 0, 0]
// ]

If you don't provide a default value, the array will be filled with null:

const myArray = twoDArray(rows, cols);

console.log(myArray);
// Output:
// [
//   [null, null, null, null],
//   [null, null, null, null],
//   [null, null, null, null]
// ]
