Question 1

How do I install and use isarray in a Node.js project?

Accepted Answer

Install it via npm with 'npm install isarray', then require it in your code: 'const isArray = require("isarray");'. This provides the Array.isArray function for Node.js versions that lack it natively, as shown in the README's usage example.

Question 2

What's the difference between isarray and using typeof for arrays?

Accepted Answer

isarray implements the standard Array.isArray method, which correctly identifies arrays even in edge cases like cross-frame objects, whereas typeof returns 'object' for arrays and is unreliable. The README emphasizes standard compliance over ad-hoc checks.

Question 3

Do I still need isarray in 2024 for web development?

Accepted Answer

For most modern projects, no—Array.isArray is natively supported in all major browsers and Node.js versions released in the past decade. Use isarray only if you specifically need to support very old environments like IE8-IE10, as the README advises.

Question 4

isarray vs lodash isArray: which should I use?

Accepted Answer

isarray is a minimal, standard-compliant polyfill for Array.isArray, while lodash's isArray is part of a larger utility library. Choose isarray if you only need this one function and want to avoid extra dependencies; lodash is better for broader utility needs.

Question 5

How to bundle isarray with webpack instead of browserify?

Accepted Answer

Install isarray via npm, then import it in your JavaScript files (e.g., 'import isArray from "isarray";'). Webpack will handle bundling automatically with standard configuration, unlike the browserify-specific mention in the README.

Question 6

Is isarray compatible with TypeScript or ES6 modules?

Accepted Answer

Yes, isarray can be used with TypeScript or ES6 imports, but you may need to handle type definitions or module resolution. For TypeScript, native Array.isArray is type-safe and preferred when possible, reducing reliance on polyfills.
