Module `web`

What every other module shares: the error codes (Web IDL exceptions and DOMException names), the exception record of the calling module, and the entry point of a page module.

Exposed to: Window, Worker. Source: api/web.widl.

Odin: import "wren:core".

Types

enum `Error` : i32

The status of a function that raises: 0, or what went wrong. Promise rejections use the same codes.

`Hierarchy`	-2	HierarchyRequestError: the node cannot go there.
`Not_Found`	-3	NotFoundError, or a null result ("no such attribute", "no such entry").
`Invalid_Argument`	-4	An argument out of its range (an enum, an index, a size).
