Common JS Array based Utilities

Install

npm i common-array-utils

API

numericArrayGenerator(size)

Creates a sequential integer array [0, 1, 2, ..., size-1].

const { numericArrayGenerator } = require('common-array-utils');
numericArrayGenerator(5); // [0, 1, 2, 3, 4]
numericArrayGenerator(0); // []

arrayGenerator(size, object)

Creates an array of size filled with shallow copies of object (default {}).

Note: Only shallow copies — nested objects still share references.

const { arrayGenerator } = require('common-array-utils');
arrayGenerator(3);            // [{}, {}, {}]
arrayGenerator(2, { a: 1 });  // [{ a: 1 }, { a: 1 }]

validArray(arr)

Returns true if the input is a non-empty array.

const { validArray } = require('common-array-utils');
validArray([1, 2]);    // true
validArray([]);        // false
validArray(null);      // false

Publishing

Pushing to master triggers automatic publish to npm via GitHub Actions (requires NPM_TOKEN secret). Only runs when package.json changes and skips if the version tag already exists.
