About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isNaNArray

Test if a value is an array-like object containing only NaN values.

Usage

import isNaNArray from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-nan-array@deno/mod.js';

You can also import the following named exports from the package:

import { objects, primitives } from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-nan-array@deno/mod.js';

isNaNArray( value )

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

var bool = isNaNArray( [ NaN, NaN, NaN ] );
// returns true

bool = isNaNArray( [ NaN, 2 ] );
// returns false

isNaNArray.primitives( value )

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

import Number from 'https://cdn.jsdelivr.net/gh/stdlib-js/number-ctor@deno/mod.js';

var bool = isNaNArray.primitives( [ NaN, NaN, NaN ] );
// returns true

bool = isNaNArray.primitives( [ NaN, new Number( NaN ) ] );
// returns false

isNaNArray.objects( value )

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

import Number from 'https://cdn.jsdelivr.net/gh/stdlib-js/number-ctor@deno/mod.js';

var bool = isNaNArray.objects( [ new Number( NaN ), new Number( NaN ) ] );
// returns true

bool = isNaNArray.objects( [ NaN, new Number( NaN ) ] );
// returns false

bool = isNaNArray.objects( [ NaN, NaN, NaN ] );
// returns false

Examples

import Number from 'https://cdn.jsdelivr.net/gh/stdlib-js/number-ctor@deno/mod.js';
import Float64Array from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-float64@deno/mod.js';
import isNaNArray from 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-nan-array@deno/mod.js';

var bool = isNaNArray( [ NaN ] );
// returns true

bool = isNaNArray( [ NaN, NaN, NaN ] );
// returns true

bool = isNaNArray( [ new Number( NaN ), NaN, NaN ] );
// returns true

bool = isNaNArray( new Float64Array( [ NaN, NaN ] ) );
// returns true

bool = isNaNArray( NaN );
// returns false

bool = isNaNArray( [ 'a', 'b', 'c' ] );
// returns false

bool = isNaNArray( [ 'a', NaN ] );
// returns false
