Pipelines in JavaScript are proposed as a new syntax for chaining operations, inspired by their use in functional languages like Elm and Elixir, and aim to improve code readability by reducing nested parentheses. Currently in Stage 1 of the ECMAScript proposal process, three main pipeline proposals are being considered: simple pipelines, which straightforwardly pass the evaluated expression from left to right; F# pipelines, which add support for asynchronous operations using `await`; and smart pipelines, which incorporate a placeholder token to enhance flexibility and handle complex nested operations. These proposals are part of a broader open-source development process within the JavaScript ecosystem, allowing developers to experiment with new features through Babel plugins and contribute feedback before features are finalized, ensuring backward compatibility and community involvement in the language's evolution.
