Package description
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.
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
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.
array-check provides functionality to determine if a value is an array, similar to isarray. However, it also includes additional features for checking if arrays are equal or if an array contains a certain value, which isarray does not provide.
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
Array#isArray
for older browsers and deprecated Node.js versions.
Just use Array.isArray directly, unless you need to support those older versions.
var isArray = require('isarray');
console.log(isArray([])); // => true
console.log(isArray({})); // => false
With npm do
$ npm install isarray
Then bundle for the browser with browserify.
