option-t/esm/deprecated/plain_option/flatten.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 { andThenForOption } from './and_then.js';
function flatten(input) {
    return input;
}
/**
 *  Flatten the inner value of _input_.
 */
export function flattenForOption(input) {
    const result = andThenForOption(input, flatten);
    return result;
}
