This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The DOMImplementation interface represents an object providing methods which are not dependent on any particular document. Such an object is returned by the Document.implementation property.
This interface has no specific property and doesn't inherit any.
No inherited method.
DOMImplementation.createDocument()Creates and returns an XMLDocument.
DOMImplementation.createDocumentType()Creates and returns a DocumentType.
DOMImplementation.createHTMLDocument()Creates and returns an HTML Document.
DOMImplementation.hasFeature() Deprecated
Returns a boolean value indicating if a given feature is supported or not. This function is unreliable and kept for compatibility purpose alone: except for SVG-related queries, it always returns true. Old browsers are very inconsistent in their behavior.
