What are the disadvantages of AngularJS?

in Learning, Tips and Tricks

Advantages of AngularJS:

  1. Open source JavaScript framework, developed by Google
  2. MVC architecture
  3. Write less do more
  4. Modify DOM directly
  5. Two way data binding
  6. Quiet a number of ways to do same thins

Disadvantages of AngularJS:

  1. Limitation in watchers (not more than 2000)
  2. Not built for mobile devices
  3. Multiple ways to do the same thing, it is very hard for a developer to tell which is the best way.
  4. Two way binding checks all the variables twice for updating which makes the UI slow

If you are new to AngularJS, I would recommend to learn Angular 2 or above.

Angular 2 is a completely rewritten of Angular 1.X so you can learn it without knowing about AngularJS or Angular 1.x.

Following are the Advantages of AngularJS

  • allows us to create a single page application
  • follows MVC pattern
  • predefined form validations
  • supports animation
  • open source
  • cross-browser compliant
  • supports two-way data binding
  • its code is unit testable

Following are the Disadvantages of AngularJS

  • JavaScript Dependent: If end user disables JavaScript, AngularJS will not work.
  • Not Secured: It is JavaScript based framework so it is not safe to authenticate user through AngularJS only.

With AngularJS, you don’t have the ability to compose many NG-apps on the same page. This can cause name clashes.

Advantages Of AngularJS

Here are some of the compelling advantages of AngularJS:

Built by Google

AngularJS has been developed as well as maintained by dedicated Google engineers. This means that there is a huge community out there for you to learn from. Apart from that, there are engineers that can help you tackle any challenges you face on the way. It also means that clients get what they want.

Great MVC

As mentioned earlier, most frameworks require programmers to splitting the app into multiple MVC components. After that, the programmer has to write a code to put them together again. AngularJS, however, strings it together automatically. That saves you time, and reduces the app’s time-to-market.

Intuitive

AngularJS is more intuitive as it makes use of HTML as a declarative language. Moreover, it is less brittle for reorganizing.

Comprehensive

AngularJS is a comprehensive solution for rapid front-end development. It does not need any other plugins or frameworks. Moreover, there are a range of other features that include Restful actions, data building, dependency injection, enterprise-level testing, etc.

Unit Testing Ready

AngularJS is unit testing ready, and that is one of its most compelling advantages.

Apart from these, there are a range of other advantages that make AngularJS as popular as it is.

Disadvantages Of AngularJS

Along with advantages, you will always come across disadvantages of any platform. That’s the case with AngularJS too.

Here’s a compilation of some of the drawbacks of using AngularJS:

Confusion

There are multiple ways to do the same thing with AngularJS. Sometimes, it can be hard for novices to say which way is better for a task. Hence, it is imperative for programmers to develop an understanding of the various components and how they help.

Lagging UI

If there are more than 2000 watchers, it can get the UI to severely lag. This means that the possible complexity of Angular Forms is limited. This includes big data grids and lists.
