MEAN (MongoDB, Express.js, AngularJS (or Angular), and Node.js) [1] is a source-available JavaScript software stack for building dynamic web sites and web applications. [2] A variation known as MERN replaces Angular with React.js front-end, [3] [4] and another named MEVN use Vue.js as front-end.
AngularJS's templating is based on bidirectional UI data binding. Data-binding is an automatic way of updating the view whenever the model changes, as well as updating the model whenever the view changes. The HTML template is compiled in the browser. The compilation step creates pure HTML, which the browser re-renders into the live view.
The rewrite of AngularJS was called "Angular 2", but this led to confusion among developers. To clarify, the team announced that separate names should be used for each framework with "AngularJS" referring to the 1.X versions and "Angular" without the "JS" referring to versions 2 and up. [21]
There are two types of binding. One-way binding should be applied when one of the properties is read-only. In other cases, two-way binding must be applied. [2] [3] Infinite loops can be eliminated by blocking the signal, or comparing the assigned value with the property value before assignment, or eliminating unnecessary assignments. [2] [3]
There are three libraries in two source files: JsRender is the template library; JsViews is the MVVM library which provides two-way data binding for the templates JsObservable is integrated with JsViews and facilitates observable data manipulations that are immediately reflected in the data-bound templates.
On 2 May 2018, the Polymer team announced that any future development in Polymer will shift away from its two-way binding and its template system, and will focus on LitElement [12] (still part of Polymer [13]) and one-way bindings. [14]
