is-arrayish

What is is-arrayish?

The is-arrayish npm package is used to determine if a value is array-like, meaning it can be iterated over like an array. This can include actual arrays, array-like objects (such as arguments or NodeList objects), or objects with a length property that are not functions.

What are is-arrayish's main functionalities?

Check if a value is array-like

This feature allows you to check if a given value is array-like. It returns true for actual arrays, array-like objects, and objects with a length property that are not functions. It returns false for other types of values, such as strings or functions.

var isArrayish = require('is-arrayish');

console.log(isArrayish([])); // true
console.log(isArrayish({ length: 1, 0: 'a' })); // true
console.log(isArrayish('string')); // false
console.log(isArrayish(function(){})); // false

Other packages similar to is-arrayish

isarray

The isarray package provides a simple utility for determining whether a given value is an array. It is similar to is-arrayish but is more strict, as it only returns true for actual Array instances.

is-arguments

The is-arguments package is designed to check if a value is an arguments object. While is-arrayish can also identify arguments objects as array-like, is-arguments is specifically tailored for this purpose and does not consider other array-like objects.
