isBuffer
Test if a value is a Buffer object.
Usage
var isBuffer = require( '@stdlib/assert/is-buffer' );
isBuffer( value )
Tests if a value
is a Buffer
object.
var Buffer = require( '@stdlib/buffer/ctor' );
var value = new Buffer( [ 1, 2, 3, 4 ] );
var bool = isBuffer( value );
// returns true
Notes
- The implementation supports both Node.js and browser polyfill
Buffer
objects.
Examples
var Int8Array = require( '@stdlib/array/int8' );
var Buffer = require( '@stdlib/buffer/ctor' );
var isBuffer = require( '@stdlib/assert/is-buffer' );
var bool = isBuffer( new Buffer( [ 1, 2, 3, 4 ] ) );
// returns true
bool = isBuffer( new Buffer( 'beep' ) );
// returns true
bool = isBuffer( [] );
// returns false
bool = isBuffer( {} );
// returns false
bool = isBuffer( new Int8Array() );
// returns false
bool = isBuffer( function foo() {} );
// returns false
bool = isBuffer( null );
// returns false
bool = isBuffer( void 0 );
// returns false
bool = isBuffer( 'beep' );
// returns false
bool = isBuffer( 5 );
// returns false
