A virtual DOM is a lightweight JavaScript representation of the Document Object Model (DOM) used in declarative web frameworks such as React, Vue.js, and Elm. [1] Since generating a virtual DOM is relatively fast, any given framework is free to rerender the virtual DOM as many times as needed relatively cheaply.
The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects.
Another notable feature is the use of a virtual Document Object Model, or Virtual DOM. React creates an in-memory data-structure cache, computes the resulting differences, and then updates the browser's displayed DOM efficiently. [31] This process is called reconciliation. This allows the programmer to write code as if the entire page is ...
VTD-XML typically consumes 1.3-1.5 times the XML document's size in memory, which is about 1/5 the memory usage of DOM [citation needed] Applications written in VTD-XML are usually much shorter and cleaner than their DOM or SAX versions. [citation needed]

Notationally, this is written as d dom n (or sometimes d ≫ n). By definition, every node dominates itself. There are a number of related concepts: A node d strictly dominates a node n if d dominates n and d does not equal n.
Live, Virtual, & Constructive (LVC) Simulation is a broadly used taxonomy for classifying Modeling and Simulation (M&S). However, categorizing a simulation as a live, virtual, or constructive environment is problematic since there is no clear division among these categories. The degree of human participation in a simulation is infinitely ...
Distributed Object Middleware (DOM) is a type of infrastructure that allows remote access to remote objects transparently. It is based on the Remote Procedure Call ( RPC ) mechanism. Some DOM systems also enable objects on different platforms to interact, for example, CORBA .
