Overview

ReScript Core

Core is ReScript's new standard library. It replaces the complete Js module as well as some of the more frequently used modules from Belt and is recommended to use with uncurried mode.

In ReScript 11, it is shipped as a separate npm package @rescript/core that is added to your project as per the installation instructions. In future ReScript versions, it will be included with the rescript npm package itself.

Additional Libraries

ReScript ships with these two additional modules in its standard library:

• Belt: immutable collections and extra helpers not available in JavaScript / Core.
• Dom: Dom related types and modules. Contains our standardized types used by various userland DOM bindings.

Legacy Modules

The Js module is superseded by Core.
