Web APIs (navigator, geolocation, history)

ACCURACY_INSUFFICIENT is not a standard Geolocation API error code: 1) The Geolocation API defines three standard error codes returned via the error.code property, 2) PERMISSION_DENIED (value 1) occurs when users reject location permission requests, 3) POSITION_UNAVAILABLE (value 2) happens when the device cannot obtain a position (e.g., no GPS signal), 4) TIMEOUT (value 3) is triggered when a position couldn't be obtained within the specified timeout period, 5) There is no standard ACCURACY_INSUFFICIENT error—accuracy concerns are typically handled through the accuracy property of successful results, 6) Developers can check the error.code against these constants (accessible as properties on the error object itself) to provide specific feedback, 7) The error object also contains a message property with a human-readable description, though this is primarily for debugging, 8) These standardized errors help developers implement appropriate fallbacks or user guidance when location requests fail.
