is-what/dist/isNaNValue.js

JS type check (TypeScript supported) functions like `isPlainObject() isArray()` etc. A simple & small integration.

import { getType } from './getType.js';
/** Returns whether the payload is literally the value `NaN` (it's `NaN` and also a `number`) */
export function isNaNValue(payload) {
    return getType(payload) === 'Number' && isNaN(payload);
}
