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