Package description

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);
