    NPM version Build Status Coverage Status dependencies

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

    Installation

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

    Usage

    var isNegativeNumberArray = require( '@stdlib/assert-is-negative-number-array' );

    isNegativeNumberArray( value )

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

    var Number = require( '@stdlib/number-ctor' );
    
    var bool = isNegativeNumberArray( [ -3.0, new Number(-3.0) ] );
    // returns true
    
    bool = isNegativeNumberArray( [ -3.0, '-3.0' ] );
    // returns false

    isNegativeNumberArray.primitives( value )

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

    var Number = require( '@stdlib/number-ctor' );
    
    var bool = isNegativeNumberArray.primitives( [ -1.0, -5.0, -10.0 ] );
    // returns true
    
    bool = isNegativeNumberArray.primitives( [ -3.0, new Number(-1.0) ] );
    // returns false

    isNegativeNumberArray.objects( value )

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

    var Number = require( '@stdlib/number-ctor' );
    
    var bool = isNegativeNumberArray.objects( [ new Number(-1.0), new Number(-1.0) ] );
    // returns true
    
    bool = isNegativeNumberArray.objects( [ -1.0, -5.0, -10.0 ] );
    // returns false

    Examples

    var Number = require( '@stdlib/number-ctor' );
    var isNegativeNumberArray = require( '@stdlib/assert-is-negative-number-array' );
    
    var bool = isNegativeNumberArray( [ -5.0, -0.2, -3.9 ] );
    // returns true
    
    bool = isNegativeNumberArray( [ -1, -2, -3 ] );
    // returns true
    
    bool = isNegativeNumberArray( [ -1, new Number( -6 ), -3 ] );
    // returns true
    
    bool = isNegativeNumberArray( [ 0, -2, -4 ] );
    // returns false
    
    bool = isNegativeNumberArray( [ -1, 'abc', -3 ] );
    // returns false
    
    bool = isNegativeNumberArray( -78.0 );
    // returns false
