Definition: "DTREE.JS" is a JavaScript library for creating dynamic tree views, similar to React, but designed specifically for web development. The word "tree," used in this context, refers to the graphical representation of an object or entity within a hierarchy system, where each node represents an attribute with its own value and children are further nodes that represent values of these attributes. In the context of dynamic tree views, the term "tree" is often used interchangeably with "node," but in this specific instance, it refers to the actual visual representation of the objects or entities within the hierarchy. The library provides a powerful way for developers to create interactive and dynamic tree views that can be customized based on user input. It's designed with features such as support for nested elements and an ability to display hierarchical relationships between nodes.
