# isNonPositiveIntegerArray > Test if a value is an array-like object containing only nonpositive integers.
## Usage ```javascript var isNonPositiveIntegerArray = require( '@stdlib/assert/is-nonpositive-integer-array' ); ``` #### isNonPositiveIntegerArray( value ) Tests if a `value` is an array-like object containing **only** nonpositive `integer` values. ```javascript var Number = require( '@stdlib/number/ctor' ); var bool = isNonPositiveIntegerArray( [ -3, new Number(-3) ] ); // returns true bool = isNonPositiveIntegerArray( [ -3, '3.0' ] ); // returns false ``` #### isNonPositiveIntegerArray.primitives( value ) Tests if a `value` is an array-like object containing **only** nonpositive primitive `integer` values. ```javascript var Number = require( '@stdlib/number/ctor' ); var bool = isNonPositiveIntegerArray.primitives( [ -1.0, -10.0 ] ); // returns true bool = isNonPositiveIntegerArray.primitives( [ -1.0, 0.0, -10.0 ] ); // returns true bool = isNonPositiveIntegerArray.primitives( [ -3.0, new Number(-1.0) ] ); // returns false ``` #### isNonPositiveIntegerArray.objects( value ) Tests if a `value` is an array-like object containing **only** `Number` objects holding nonpositive `integer` values. ```javascript var Number = require( '@stdlib/number/ctor' ); var bool = isNonPositiveIntegerArray.objects( [ new Number(-1.0), new Number(-10.0) ] ); // returns true bool = isNonPositiveIntegerArray.objects( [ -1.0, 0.0, -10.0 ] ); // returns false bool = isNonPositiveIntegerArray.objects( [ -3.0, new Number(-1.0) ] ); // returns false ```
## Examples ```javascript var Number = require( '@stdlib/number/ctor' ); var isNonPositiveIntegerArray = require( '@stdlib/assert/is-nonpositive-integer-array' ); var bool = isNonPositiveIntegerArray( [ -5, -2, -3 ] ); // returns true bool = isNonPositiveIntegerArray( [ -4, -3, -2, -1 ] ); // returns true bool = isNonPositiveIntegerArray( [ -1, new Number( -6 ), -3 ] ); // returns true bool = isNonPositiveIntegerArray( [ -3, -2, -1, 0 ] ); // returns true bool = isNonPositiveIntegerArray( [ -3, -2, -1, 0, 2 ] ); // returns false bool = isNonPositiveIntegerArray( [ -1, 'abc', -3 ] ); // returns false bool = isNonPositiveIntegerArray( [ -2.3, -1, -3 ] ); // returns false bool = isNonPositiveIntegerArray( [] ); // returns false ```
