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!
alloc
Allocate a buffer having a specified number of bytes.
Installation
npm install @stdlib/buffer-alloc-unsafeUsage
var allocUnsafe = require( '@stdlib/buffer-alloc-unsafe' );allocUnsafe( size )
Unsafely allocates a buffer having a specified number of bytes.
var buf = allocUnsafe( 10 );
// returns <Buffer>Notes
- The underlying memory of returned
Bufferinstances is not initialized. Memory contents are unknown and may contain sensitive data. - When the
sizeis less than half the pool size (specified on theBufferconstructor in modern Node.js environments), memory is allocated from theBufferpool for faster allocation of newBufferinstances.
Examples
var allocUnsafe = require( '@stdlib/buffer-alloc-unsafe' );
var buf;
var i;
// Repeatedly unsafely allocate memory and inspect the buffer contents...
for ( i = 0; i < 100; i++ ) {
buf = allocUnsafe( 100 );
console.log( buf.toString() );

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.
