What is typedarray?
The typedarray package provides a polyfill for TypedArray functionality that is available in modern browsers. It allows for the manipulation of binary data in a similar way to how it's done in native implementations.
What are typedarray's main functionalities?
Buffer creation
This feature allows for the creation of a buffer with a specified size. In this case, a Uint8Array with 1024 bytes is created.
var typedarray = require('typedarray');
var uint8 = new typedarray.Uint8Array(1024);
Buffer manipulation
This feature allows for the manipulation of the buffer's contents. Here, the first byte is set to 255 and the second byte to 0.
var typedarray = require('typedarray');
var buffer = new typedarray.Uint8Array(2);
buffer[0] = 255;
buffer[1] = 0;
Buffer slicing
This feature allows for the slicing of the buffer, creating a new view of the original buffer without copying the underlying memory. In this example, a slice from the second byte to the third byte is created.
var typedarray = require('typedarray');
var buffer = new typedarray.Uint8Array(4);
var slice = buffer.subarray(1, 3);
Other packages similar to typedarray
buffer
The 'buffer' package provides similar functionality for handling binary data in Node.js. It is a Node.js core module, so it's more commonly used and has a broader API than 'typedarray'.
arraybuffer
The 'arraybuffer' package offers a minimalistic implementation for array buffer which is similar to typed arrays. It is less known and has fewer features compared to 'typedarray'.
feross-buffer
The 'feross-buffer' package is a 'buffer' module from feross, which is browser-friendly. It's a drop-in replacement for Node's buffer module but designed to be used in the browser, similar to 'typedarray'.
