"isarray" is a JavaScript utility that provides Array#isArray functionality for older browsers and deprecated Node.js versions. It is crucial for developers wanting to ensure their scripts maintain compatibility across various platforms, including those with outdated JavaScript support. However, for modern environments, developers are encouraged to use Array.isArray directly.
To use "isarray", you can install it via npm using the command npm install isarray. Once installed, you can require it in your script and use as the following examples demonstrate:
var isArray = require('isarray');
console.log(isArray([])); // Outputs: true
console.log(isArray({})); // Outputs: false
It's a straightforward tool that checks if the provided input is an array, returning true or false.
Unfortunately, no explicit documentation is provided for "isarray". However, the utility's functionality is rather straightforward, and its usage examples given in the README file found on the package's GitHub repository should suffice for most developers' needs. As ever, make sure to test the utility in your specific project setup to ensure it behaves as expected.
