A collection of assertions for test and production code alike.

const checkMethods = Object.assign({}, ...guardOverrides.map((entry) => {
    return entry.check;
}));
/**
 * A group of guard methods that return a boolean type guard rather than an assertion type guard.
 *
 * This can also be called as a standalone check function which returns a boolean to indicate
 * whether its input is truthy or not.
 *
 * @category Assert
 * @category Package : @augment-vir/assert
 * @example
 *
 * ```ts
 * import {check} from '@augment-vir/assert';
 *
 * const value: unknown = 'some value' as unknown;
 * if (check.isString(value)) {
 *     // `value` will now be typed as a `string` in here
 * }
 * ```
 *
 * @returns A boolean (as a type guard when possible).
 * @package [`@augment-vir/assert`](https://www.npmjs.com/package/@augment-vir/assert)
