The "typedarray" is a polyfill JavaScript package that is optimized for older browsers. It provides functionality that is normally available in newer browsers to older ones by emulating built-in typed arrays, such as Uint8Array, Int32Array, etc. This can be particularly useful when creating complex applications that require high-performance numeric calculations.
To utilize the "typedarray" package in your JavaScript code, you must first install it via npm with the command npm install typedarray
. Once installed, you can require it in your JavaScript file using var TA = require('typedarray')
. You can then create an instance of any typed array available via the TA
object. Here's an example of how to create a Uint8Array and set a value:
var Uint8Array = require('typedarray').Uint8Array;
var ua = new Uint8Array(5);
ua[1] = 256 + 55;
console.log(ua[1]); // Outputs: 55
And here's how to instantiate other typed arrays like Float64Array, Int16Array, etc:
var Float64Array = require('typedarray').Float64Array;
var Int16Array = require('typedarray').Int16Array;
// You can now create arrays using these constructors
var fa = new Float64Array(5);
var ia = new Int16Array(5);
Please take note that typed arrays in JavaScript are used to handle numeric data types that are stored in an array-like structure.
While the "typedarray" package does not appear to have detailed documentation within its GitHub repository, the usage examples and method constructors given in the readme provide a basic understanding of how to use the package. For a more thorough understanding of what typed arrays are and how they can be used, the Mozilla Developer Network provides detailed documentation on Typed Arrays in JavaScript.
