option-t/esm/undefinable/operators/inspect.js

A toolkit of Nullable/Option/Result type implementation in ECMAScript. Their APIs are inspired by Rust's `Option<T>` and `Result<T, E>`.

import { isNotUndefined } from '../core/undefinable.js';
/**
 *  * Return _input_ directly.
 *      * This value is passed as the input. But it maybe mutated by calling _effector_.
 *  * Call _effector_ with _input_ if _input_ is not `undefined`.
 *
 *  * This was added to sort with others or future enhancement to accept chaining functions.
 *    We recommend to use simple `if` statement or similar way and they would be more efficient.
