10 Reasons Web Developers Should Learn AngularJS

10 Reasons Web Developers Should Learn AngularJS

1. AngularJs Gives you XAML Developers a Place to Go on the Web.

I make this projectile a bit "tongue-in-cheeck" in light of the fact that most of designers utilizing Angular likely have not contacted XAML with a 10 foot shaft.That is ok,the reasons why XAML wound up mainstream in the Microsoft world through WPF,Silverlight, and now Windows Store application improvement are essential to take a gander at in light of the fact that they make an interpretation of very well to Angular.

If you are not familier with XAML,it is a declarative language based on XML used to instantiate object graphs and set values.You can define various types of objects with properties and literally mark up a set values.You can define various types of objects with properties and literally mark up a set that will get created. The most widely recognized sorts of items to make are UI components, for example, boards and controls that make a showcase..XAML makes it easy to layout complex UI's that may change over time. XAML bolsters legacy (properties characterized as offspring of guardians can get qualities set higher in the tree) and air pockets occasions like the HTML DOM.

2.AngularJS Gets Rid of Ritual and Ceremony

Have you ever created a text property on a model that you want to bind to your UO?How is that done in various frameworks? In Angular, this will work with no issues and quickly reflect what you type in the range:

[code language="html"]

{{synchronizeThis}}

[/code]

Obviously you will only from time to time have the advantage of structure an application that simple,but it shows how simple and clear information restricting can be in the Angular world. There is next to no custom or function associated with standing up a model that takes an interest in information authoritative. You don't need to get from a current article or unequivocally pronounce your properties and conditions - for the most part, you can just pass something you already have to Angular and it just works.That's very powerful.If you are curious how it works,Angular uses dirty tracking.

3.

AngularJS Handles Dependencies

Dependency injection is something Angular does quite well. I will admit I was skeptical we even needed something like that on the client,but I was used to the key scenario being the dynamic loading of modules.Oh,wait -what did you say?That's right,with libraries like RequireJS you can dynamically load Javascript if and when you need it.where dependency injection really shines however is two scenarios :testing and Single Page Application.

4.

AngularJS Allows Developers to Express UI Declaratively and Reduce the Side Effects.

There are numerous points of interest to a decisive UI.I referenced a few when I talked about XAML before in this post,but HTML is in the equivalent boat. Having a structures UI makes it more obvious and manipulate.Designers who are not really software engineers can learn markup far simpler than they can programming.Using jQuery you wind up knowing a great deal about the structure of your archives. This makes two issues : first,the result is a great deal of unsteady code filling in as "stick" that is firmly coupled to changes in the UI, and second, you end with bounty "enchantment " in light of the fact that it's not evident from taking a gander at the markup exactly what the UI will do.In other words,you may have a lot of behaviours and animations that are wired up "behind the scenes" so it is not apparent from looking at the form tags that any validation or transitions are taking place.

5.

AngularJS Embraces DD... Er, Testing

It doesn't make a difference in the event that you grasp Test-Driven Development,Behaviour-Driven Development, or any of the determined improvement methodologies,Angular grasps this way to deal with structure your appplication. I would prefer not to utilize this post to get into the majority of the preferences and reasons why you should test (I'm really astounded that in 2013 people,still question the worth) yet I've as of late taken unquestionably all the more a customary "test-first" approach and it is made a difference.I believe that on our project,the introduction of Jasmine and tests we included were responsible for reducing defects by up to 4x. Possibly it is less (or it could be more) however there was a huge drop-off. This isn't a direct result of Angular - it is tests accurately and after that having the system to run them - however it absolutely was simpler to construct those tests.

6.

AngularJS enables Massively Parallel Development

One of the biggest issues we encountered early in the project was developers stepping on each other's toes.Some portion of this is only a disciplie and even with crude Javascript you can pursue designs that make it more modular,but Angular just took it to another level. This isn't to imply that it totally wipes out dependencies,but it unquestionably makes them simpler to oversee. As a particular case in point,there is a monstrous matrix in the application that is utilized to drive a few key operations.In a conventional Javascript application it could have been a union bad dream to scale this over a huge group. With Angular,however,it was direct to separate the different activities into their very own administrations and sub-controllers that engineers could freely test and code without colliding with one another as regularly.
