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!

isBuffer

Test if a value is a Buffer object.

Installation

1npm install @stdlib/assert-is-buffer

Alternatively,

To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
If you are using Deno, visit the deno branch (see README for usage intructions).
For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

1var isBuffer = require( '@stdlib/assert-is-buffer' );

isBuffer( value )

Tests if a value is a Buffer object.

1var Buffer = require( '@stdlib/buffer-ctor' );
2
3var value = new Buffer( [ 1, 2, 3, 4 ] );
4
5var bool = isBuffer( value );
6// returns true

Notes

The implementation supports both Node.js and browser polyfill Buffer objects.

Examples

1var Int8Array = require( '@stdlib/array-int8' );
2var Buffer = require( '@stdlib/buffer-ctor' );
3var isBuffer = require( '@stdlib/assert-is-buffer' );
4
5var bool = isBuffer( new Buffer( [ 1, 2, 3, 4 ] ) );
6// returns true
7
8bool = isBuffer( new Buffer( 'beep' ) );
9// returns true
10
11bool = isBuffer( [] );
12// returns false
13
14bool = isBuffer( {} );
15// returns false
16
17bool = isBuffer( new Int8Array() );
18// returns false
19
20bool = isBuffer( function foo() {} );
21// returns false
22
23bool = isBuffer( null );
24// returns false
25
26bool = isBuffer( void 0 );
27// returns false
28
29bool = isBuffer( 'beep' );
30// returns false
31
32bool = isBuffer( 5 );
33// returns false

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.
