angular js-what is the hype?!

By Lisa G

Angular (AngularJS) is a powerful JavaScript framework used to develop Web Applications. Remember back in the day, when websites were organized and formed with only some static pages? If you do, then you can understand, how everything has changed. It is the era of Web Applications, and those are more efficient and dynamic than the static web pages. Here comes the AngularJS. It can help a single page static HTML website to convert into an active Web Application. Angular is a framework that extends HTML’s syntax to let your application’s segments to be expressed clearly and accurately. There are various reason to choose Angular as the best framework to develop Web Applications. The first thing is, it has been developed and monitoring by Google engineers. A large community and genius engineers are ready to help the new users and improve the framework's features. It means the user will get what they are looking for their Web space. Developers also prefer its mandate injection as well as the data binding, as this ensures that a large part of the code that a programmer will write is now eliminated/automated. For the consumers, it can save valuable times. It offers the developers to the higher level of abstraction also goes an extended way in clarifying app development and reducing development time. AngularJS can be used when you are building a CRUD client side application.

Advantages of AngularJS:

The first benefit of AngularJS is Google.Inc developed it. So, you mustn't worry about the reliability and efficiency of the Angular framework. There are various frameworks available which were designed by some amateur or hobbyist programmers, but Angular is opposite, dedicated Google engineers worked hard to develop and improve its efficiency. It is maintained by the Google engineers, and even though you may not have access to remove your doubts and post your queries, you have the advantage of gaining the instructions from highly skilled and talented developers and programmers.

 

Learning and using AngularJS is pretty much easier like HTML. You can use HTML properties to access AngularJS directives. You can add a few attributes to your HTML and reap the exhibitions of a simple Angular application in as enough as five minutes.

 

Another feature of AngularJS is to do two-way data binding. It means you can apply any data related changes which will be implemented immidietly. As soon as the app data are modified by the user, the whole application User Interface will change too.

 

The built-in dependency injection is the feature that most developers prefer about AngularJS. It helps programmers and developers to develop, understand and test Web Apps in an understanding way. It also has the DI feature, so a developer don't need to worry about dependencies. Or make those by themselves, but would be made and brought to you. To assure, you have all the AngularJS’s core features; you can only add that parameter and customize it as you require.

 

The directives AngularJS is a particular advantage for many programmers. AngularJS can create custom HTML tags and decorate the elements with browsers, so you don't have to just dream about creating custom tags, it's now the reality with Angular. And, you can also handle DOM attributes in numerous provocative ways.

 

When you are working with HTML and data on your web pages, client-side MVC framework will be an important framework to manage. MVC framework can help developers to manage web page interactions and data collections. Here comes the role of Angular. It has the best solution to create the balance between client-side and server-side. AngularJS enables you to quickly edit client-side web applications by utilizing the significant sources in the MVC software design patterns. 

 

There are so many filters available in AngularJS. Filters typically transform data. Some of the built-in filters are:

  • OrderBy,
  • Number,
  • Date,
  • Uppercase,
  • Jason,
  • Currency,
  • LimitTo,
  • Lowercase, etc.

The user-define filter can be built from factory function when developers will work with modules.

 

Disadvantages of AngularJS:

Along with the advantages, you may face some problems on any platform. Angular has it too. Here are some of the drawbacks of AngularJS:

 

There are various methods available to do the same thing on AngularJS with libraries. So, sometimes, it can be hard for beginners to say which library or method is better for a particular task. Hence, it is important for programmers to develop an understanding of the various elements of a framework and how those can help.

 

With AngularJS, it is not possible to write multiple NG-apps code on the same page. It can often cause name clashes.

 

If you use more than 2000 watchers in an application, it may cause to lag the User Interface. It means the complexity of Angular Form is limited.

 

As discussed above, AngularJS only needs you to is, break your application into multiple MVC components. Once you are finished with that, AngularJS will take over and do the rest of the functions for you. It saves you from the trouble of writing another code to bind the MVC components together again. And, another point is, with AngularJS data-binding happens swea-free and you will see whatever you write on the span immediately. So, it is worth learning AngularJS from now.
