Document.all

The Document interface's read-only all property returns an HTMLAllCollection rooted at the document node. In other words, it returns all of the document's elements, accessible by order (like an array) and by ID (like a regular object).

Syntax

var htmlAllCollection = document.all;

Value

An HTMLAllCollection which contains every element in the document.

Conversion to boolean

document.all is the only falsy object accessible to JavaScript, because it has the [[IsHTMLDDA]] internal slot. This was done because of compatibility with older versions of Internet Explorer. More information about this can be found in this answer from StackOverflow.
