About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
copyBuffer
Copy buffer data to a new Buffer instance.
Installation
npm install @stdlib/buffer-from-buffer
Usage
var copyBuffer = require( '@stdlib/buffer-from-buffer' );
copyBuffer( buffer )
Copies buffer data to a new Buffer instance.
var array2buffer = require( '@stdlib/buffer-from-array' );
var b1 = array2buffer( [ 1, 2, 3, 4 ] );
// returns <Buffer>[ 1, 2, 3, 4 ]
var b2 = copyBuffer( b1 );
// returns <Buffer>[ 1, 2, 3, 4 ]
Examples
var allocUnsafe = require( '@stdlib/buffer-alloc-unsafe' );
var copyBuffer = require( '@stdlib/buffer-from-buffer' );
var bool;
var b1;
var b2;
var i;
// Allocate a new buffer:
b1 = allocUnsafe( 10 );
// Generate a new buffer from the existing buffer:
b2 = copyBuffer( b1 );
bool = ( b2 === b1 );
// returns false
bool = ( b2.length === b1.length );
// returns true
for ( i = 0; i < b2.length; i++ ) {
console.log( b2[ i ] === b1[ i ] );
// => true
}
Notice
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
