Desktop: Desktop-installed apps across Mac, Windows, and Linux can be created using the same Angular methods like the web plus the ability to access native OS APIs.

Speed and Performance

  • Code Generation: Angular turns templates into code that’s highly optimized for JavaScript virtual machines, giving hand-written code benefits.
  • Universal: Serve the first view ofNode.js, .NET, PHP, and other servers for near-instant rendering in just HTML and CSS.
  • Code Splitting: With the new Component Router, angular apps load quickly, delivering automatic code-splitting. So users load the code required to render the view they request.


  • Templates: create UI views with simple and powerful template syntax.
  • Angular CLI: Commandline tools: start building fast, add components and tests, then instantly deploy.
  •  IDEs: Get intelligent code completion, instant errors, and other feedback in popular editors and IDEs.

Full DevelopmentStory 

  • Testing: Protractor makes your scenario tests run faster and in a stable manner.
  • Animation: Create high-performance, complex choreographies, and animation timelines with very little code through Angular’s intuitive API.
  • Accessibility: Create accessible applications with ARIA-enabled components, developer guides, and built-in a11y test infrastructure.

  • Declarative:

Creates interactive and dynamic UI for web sites and cell applications. React updates expeditiously and render the precise components as soon as expertise changes. Declarative perspectives create the code legible and easy to debug.

  • Virtual DOM:

  • Event handling:

React has its all like-minded W3C item version occasion machine It collectively gives a cross-browser interface to a local occasion, that shows no want to fear concerning incompatible occasion names, React reduces reminiscence head with the aid of using as occasion machine is applied via occasion delegation and consists of a pool of occasion objects.

  • JSX:

  • React Native:

React Native is a custom renderer for React; it makes use of local additives in preference to internet additives like React as constructing blocks. It additionally serves to get admission to those platforms’ features, other than reworking React code to paintings on iOS and Android.

Methods do now no longer hold information of any dependencies however can take arguments.

Complexity: Vue.js is less complicated in phrases of API and design. A net developer builds simple programs in a day.

4. Ember.js 

The advent ofEmber.js to the pc code marketplace became 2015, and in reading that then, it is received nice with its extensive software area. The alternatives of Ember. J said two-manner expertise binding and hence, set up a dependable platform for managing the state-of-the-art User Interfaces. not unusual place websites like LinkedIn, Netflix, Nordstrom, and masses of extra use the Ember.

IsomorphicJavaScript CodeThe identical code may be used at the front-quit, the back-quit, and cell and net programs. It saves builders from requiring to put in and configure unique module managers, libraries, drivers, APIs, and more.  With Meteor, builders can leverage JavaScript’s electricity at the same time as lowering code period and complexity, saving a lot of manufacturing time of builders to carry out context switching among server language and JavaScript.

Front-quit Solution

Meteor gives a front-quit improvement framework, Blaze. js, which gives a few beneficial features.  It additionally integrates with famous current front-quit frameworks like Backbone.js to yield higher results.
