It allows programmer to extend HTML attributes by using Angular directives or creating custom directives. AngularJS compiler, compiles and renders HTML, it manipulates DOM elements and attach features provided in used directive.
The core feature of AngularJS is two-way data binding. It allows software programmer to create synchronized environment between view and model. If value of model is changed then it will automatically get updated in view and vice versa.
|Two-way data binding simplifies process of developing complex web applications.||Performance issues for large web applications due to constant synchronization between view and model|
|Directives allow user to manipulate DOM elements very easily||Code is difficult to understand and debug.|
|Good documentation and support||Substantial framework size|
|Very powerful framework with Filters, Dependency Injection, Expressions etc.|
React.js is the answer for building large scale applications. Unlike AngularJS, it is very efficient at rendering complex user interfaces with better performance.
Virtual DOM is the basic concept on which ReactJS works. It renders virtual DOM to server first and then compare virtual DOM with actual DOM and update only the differences. This makes it better choice for large web applications.
Facebook and Instagram are very good example of large scale web applications that are built using ReactJS.
|Light weight framework||Programmer may face issues working with other DOM manipulation libraries like jQuery.|
|Easy and simple to learn and master||Constant re-rendering of components may slow down the application in case of large set of data.|
|Highly compatible with MVC||Substantial framework size|
|High maintainability due to on-way data flow|
|Component constant re-rendering decreases complexity by providing efficient arrangement.|
EmberJS works on principle of two-way binding, just like AngularJS. It also provides synchronized environment between view and model.
To overcome performance limitation of two-way binding in complex UI rendering, Ember released module Fastboot.js that allows server side DOM rendering similar to ReactJS.
|Very popular like Angular and React so add-ons are easily available||Not as powerful or feature rich as AngularJS|
|Two-way binding and UI rendering||Difficult to learn and implement|
MeteorJS comes fully equipped with all the features that developer needs to create frontend, backend, business logic, and database management. This is supported by huge community that is always reachable for any issue or help required.
The Server side packages run in node.js. Any changes in database are reflected back to UI in real time and vice versa making database operations faster.
|Tutorials, help and custom packages are available very easily|
AureliaJS is an open source front-end technology managed by Durandal Inc. It extends the capabilities of DurandalJS. They have added libraries, tools, and frameworks to support latest web app development. It is easy to migrate to AureliaJS for developers working on AngularJS or DurandalJS.
AureliaJS has highly modularized structure. It comprises of many independent small libraries. So, one can have option to either use entire framework or use few of the required libraries or extend the libraries to create custom framework.
|Has very less dependencies as it is a self-contained package||Not suitable for small projects|
|Provides out of the box support to Typescript|
|Provides excellent routing|
|Easy to understand|
|Great documentation and support|
PolymerJS is different from others. It is released and managed by Google. It works on the concept of web components to extend capabilities of HTML.
Web component is a browser technology using which user can create new custom HTML elements.
PolymerJS provides structure and gives power to user to easily create custom HTML elements using browser based technologies like web components, Service Workers and etc.
KnockoutJS works with MVVM pattern that makes it a bit different from Angular and Ember.
|Lightweight, Small framework with no dependencies||New features are coming slowly as compared to competitor frameworks like React and Angular|
|Provides features like Binding, UI refresh, Dependency tracking and many more|
|Widely used by many communities so support is easily available|
|Great documentation and help|
|Great documentation and support|
|Easy to integrate with current project||Not suitable to use as core framework as it isn`t that feature rich. Can be used as side framework.|
|Small sized, flexible and easy to learn||Sluggish release cycle|
|Can be used to handle large projects||Lack of support|
VueJs is relatively new as compared to its competitors like Angular and React. It works with MVVM pattern.
It has very simple API that is easy to learn and also light weighted. It allows user to use entire framework or selective modules as required. It is inspired by AngularJS, ReactJS, KnockoutJS and also supports two-way binding to synchronize model and view.
|Supports two-way binding||Not very popular|
|Updates are regular to compete with other frameworks||Less support|
|Lightweight, easy to learn and versatile||Limited customizations possibility|
These are front end technologies so software development companies should take appropriate security measures to ensure safe and secure user experience.
