NPM version Build Status Coverage Status

Test if a value is an array-like object containing only negative integers.

Installation

npm install @stdlib/assert-is-negative-integer-array

Usage

var isNegativeIntegerArray = require( '@stdlib/assert-is-negative-integer-array' );

isNegativeIntegerArray( value )

Tests if a value is an array-like object containing only negative integer values.

var Number = require( '@stdlib/number-ctor' );

var bool = isNegativeIntegerArray( [ -3, new Number(-3) ] );
// returns true

bool = isNegativeIntegerArray( [ -3, '3.0' ] );
// returns false

isNegativeIntegerArray.primitives( value )

Tests if a value is an array-like object containing only negative primitive integer values.

var Number = require( '@stdlib/number-ctor' );

var bool = isNegativeIntegerArray.primitives( [ -1.0, -10.0 ] );
// returns true

bool = isNegativeIntegerArray.primitives( [ -1.0, 0.0, -10.0 ] );
// returns false

bool = isNegativeIntegerArray.primitives( [ -3.0, new Number(-1.0) ] );
// returns false

isNegativeIntegerArray.objects( value )

Tests if a value is an array-like object containing only Number objects holding negative integer values.

var Number = require( '@stdlib/number-ctor' );

var bool = isNegativeIntegerArray.objects( [ new Number(-1.0), new Number(-10.0) ] );
// returns true

bool = isNegativeIntegerArray.objects( [ -1.0, 0.0, -10.0 ] );
// returns false

bool = isNegativeIntegerArray.objects( [ -3.0, new Number(-1.0) ] );
// returns false

Examples

var Number = require( '@stdlib/number-ctor' );
var isNegativeIntegerArray = require( '@stdlib/assert-is-negative-integer-array' );

var bool = isNegativeIntegerArray( [ -5, -2, -3 ] );
// returns true

bool = isNegativeIntegerArray( [ -4, -3, -2, -1 ] );
// returns true

bool = isNegativeIntegerArray( [ -1, new Number( -6 ), -3 ] );
// returns true

bool = isNegativeIntegerArray( [ -3, -2, -1, 0 ] );
// returns false

bool = isNegativeIntegerArray( [ -1, 'abc', -3 ] );
// returns false

bool = isNegativeIntegerArray( [ -2.3, -1, -3 ] );
// returns false

bool = isNegativeIntegerArray( [] );
// returns false
