In the IndexedDB API, an IDBDatabaseException object represents exception conditions that can be encountered while performing database operations.
If an error occurs while the database connection is being opened, then an error event is fired on the request object returned from this method.
Represents a DTD notation (read-only). May declare format of an unparsed entity or formally declare the document's processing instruction targets. Inherits methods and properties from Node. Its nodeName is the notation name. Has no parent.
This page lists features of JavaScript that are deprecated (that is, still available but planned for removal) and obsolete (that is, no longer usable).
The Array.observe() method was used for asynchronously observing changes to Arrays, similar to Object.observe() for objects. It provided a stream of changes in order of occurrence. It's equivalent to Object.observe() invoked with the accept type list ["add", "update", "delete", "splice"]. However, this API has been deprecated and removed from Browsers. You can use the more general Proxy object instead.
The Array.unobserve() method was used to remove observers set by Array.observe(), but has been deprecated and removed from Browsers. You can use the more general Proxy object instead.
The Number.toInteger() method used to evaluate the passed value and convert it to an integer, but its implementation has been removed.
The Object.eval() method used to evaluate a string of JavaScript code in the context of an object, however, this method has been removed.
The Object.getNotifer() method was used to create an object that allows to synthetically trigger a change, but has been deprecated and removed in browsers.

The goal of ParallelArray was to enable data-parallelism in web applications. The higher-order functions available on ParallelArray attempted to execute in parallel, though they may fall back to sequential execution if necessary. To ensure that your code executes in parallel, it is suggested that the functions should be limited to the parallelizable subset of JS that Firefox supports.
The ElementTraversal interface was defining methods allowing to access from one Node to another one in the document tree.
