Differences Between Documentation Sites

Here’s a breakdown of the differences between the Component Library and the reference section of this developer guide.

The Component Library is the place to find reference information and interactive examples. The Reference section in this Developer Guide provides information on system-level tags that are not available elsewhere, as well as the JavaScript API.

Components in custom namespaces display both global and non-global attributes and methods in the authenticated Component Library displayed in an org. Components in managed and unmanaged packages display only global attributes and methods.
