isBuffer

Test if a value is a Buffer object.

Usage

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

isBuffer( value )

Tests if a value is a Buffer object.

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 isBuffer = require( '@stdlib/utils/is-buffer' );

console.log( isBuffer( new Buffer( [1,2,3,4] ) ) );
// returns true

console.log( isBuffer( new Buffer( 'beep' ) ) );
// returns true

console.log( isBuffer( [] ) );
// returns false

console.log( isBuffer( {} ) );
// returns false

console.log( isBuffer( new Int8Array() ) );
// returns false

console.log( isBuffer( function foo(){} ) );
// returns false

console.log( isBuffer( null ) );
// returns false

console.log( isBuffer( undefined ) );
// returns false

console.log( isBuffer( 'beep' ) );
// returns false

console.log( isBuffer( 5 ) );
// returns false
