option-t/esm/nullable/index.js

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

//  To keep a simple API set,

//  We may reconsider it if pipeline operator syntax proposal is advanced to the standard.
//  But please import them directly from their path at this moment.
