isarray

What is isarray?

The isarray package is a minimalistic npm package used to determine if a given value is an array. It is particularly useful when you need to support older browsers or environments that do not have Array.isArray available.

What are isarray's main functionalities?

Check if a value is an array

This feature allows you to check if a value is an array. It returns true if the value is an array, and false otherwise.

var isArray = require('isarray');
console.log(isArray([])); // true
console.log(isArray({})); // false

Other packages similar to isarray

lodash.isarray

This package is a part of the Lodash library, which is a more comprehensive utility toolkit. Lodash's isArray function is similar to isarray, but it comes within a larger set of utility functions. Lodash is generally larger in size compared to the standalone isarray package.

is-arrayish

is-arrayish checks if a value is array-like, meaning it's not strictly an array but can be treated like one (e.g., arguments object, NodeList). This is different from isarray, which strictly checks for actual Array instances.

README

isarray

Array#isArray for older browsers and deprecated Node.js versions.

Just use Array.isArray directly, unless you need to support those older versions.

Usage

var isArray = require('isarray');

console.log(isArray([])); // => true
console.log(isArray({})); // => false

Installation

With npm do

$ npm install isarray

Then bundle for the browser with browserify.
