Technical explanation
Each row checks for the relevant global, method, or constructor. Some features are only usable in a secure context; the page reports that separately where possible.
A constructor can exist while the underlying hardware or permission is unavailable. Use the individual tool pages for functional tests.

A feature appears supported but fails
The API may need a permission, hardware, or user gesture.
Results change after an update
