{{ APIRef("HTML DOM") }}
The HTMLTitleElement interface is implemented by a document's {{ HTMLElement( "title" )}}. This element inherits all of the properties and methods of the {{domxref("HTMLElement")}} interface.
{{InheritanceDiagram}}
Inherits properties from its parent, {{domxref("HTMLElement")}}.
No specific method; inherits methods from its parent, {{domxref("HTMLElement")}}.
Do not confuse: document.title with document.querySelector('title')
The former is just a setter/getter method to set or get the inner text value of the document title, while the latter is the HTMLTitleElement object. So you cannot write: document.title.text = "Hello world!";
Instead, you can simply write: document.title = "Hello world!"; which is an equivalent to document.querySelector('title').text = "Hello world!";
