extend¶
Under Construction
This documentation is auto-generated, and is a work in progress. Please see the source code at https://github.com/phetsims/phet-core/blob/main/js/extend.ts for the most up-to-date information.
Overview¶
Like Underscore's _.extend and PHET_CORE/merge, but with hardcoded support for ES5 getters/setters. In general this type shouldn't be used for phet's options pattern, and instead was designed to support extension for defining mixins and object prototypes.
