The npm package "is-typedarray", available at git://github.com/hughsk/is-typedarray.git, is designed to ascertain whether a given object is a Typed Array or not. Typed Arrays in JavaScript are array-like objects and provide a mechanism for accessing raw binary data. They can considerably improve the performance when you are working with sizable, contiguous blocks of data.
The "is-typedarray" package is pretty straightforward to use. First, you need to install it via npm using the command npm install is-typedarray. Once installed, you can make use of it in your JavaScript code. Here is a simple example:
var isTypedArray = require('is-typedarray');
console.log(isTypedArray(new Uint8Array())); // Outputs: true
console.log(isTypedArray([])); // Outputs: false
In these examples, isTypedArray() function is used which returns true if the given array is a Typed Array and false otherwise.
Unfortunately, an extensive documentation for "is-typedarray" is not available. The README file in the GitHub repository provides the basic usage of the package but does not provide detailed information. However, given the simplicity and the single-purpose nature of the package, this brief instruction in the README should be sufficient for most users. For more details about Typed Arrays in general, consider visiting Typed Arrays in JavaScript on the Mozilla Developer Network.
