AngularJS and ReactJS

What Is AngularJS?

AngularJS is a structured framework that has been designed for dynamic web applications. With AngularJS programmer use HTML as a template language and can express their applications components clearly by extending HTMLs syntax. AngularJS is an ideal partner with any server technology, its data binding and dependency injection features eliminate the need to write the excessive code and it all happens within the browser.

HTML does not contain much in the way of creating applications but it is a great declarative language for static documents. And as a result impedance mismatch between dynamic applications and static documents occurs. AngularJS attempts to solve this problem of impedance mismatch between HTML and application by creating new HTML constructs we call as directives. AngularJS teaches the browser new syntax through a directive.

For Example: Grouping of HTML into reusable components.

AngularJS Advantages:

  • AngularJS presents a higher level of abstraction and hence simplifies application development to the developer
  • No need to use observable functions
  • AngularJS is faster, instead of adding inner HTML code it modifies the page DOM directly
  • Data binding occurs at particular points of the JavaScript code execution instated of each control or value change
  • AngularJS has extended features such as dependency injection, orchestration, routing, animations, view and more
  • Supported by IntelliJ IDEA and Visual Studio .NET IDEs

AngularJS Disadvantages:

  • Angular is big and complicated
  • The lifecycle of AngularJS web application is complex, and to understand it developer really need to read the code
  • Compile and link are not intuitive, and specific cases can be confusing
  • Games and GUI editors are CRUD apps and as a result are probably not a good fit for AngularJS

What Is ReactJS?

ReactJS is an open source JavaScript library. It is used for building reusable UI components. ReactJS creates reusable UI components, which present data that change over time. ReactJS offers a simpler programming model and better performance by abstracting DOM. By using the React Native, it can power the native apps. Using Nodes ReactJS can render on the server. React reduces the boilerplate by implementing one-way reactive data flow, which is easier than the traditional data binding.

It helps programmers to create large web applications which can change the data without reloading the page. It is used for handling view layer for single page web application and mobile apps means it works only on the user interface in web application. ReactJS worked with the view in the MVC template so it can be used in combination of other frameworks or JavaScript libraries such as AngularJS.

ReactJS Advantages:

  • ReactJS is just simpler to grasp
  • It uses virtual DOM instead regular DOM to improve apps performance, since JavaScript virtual DOM is faster
  • ReactJS can be used with other frameworks as well as on client and server side
  • ReactJS helps to maintain larger applications by improving readability using component and data patterns

ReactJS Disadvantages:

  • ReactJS only covers the view layer of the web application, hence programmer still needs to choose other technologies for application develop0ment
  • It uses inline templating and JSX, which can awkward to some developers
  • There is no predefined way to structure web application such as services, controllers & views in Angular
