If you're familiar with Angular, this post might provide you with some ideas to think about that you hadn’t encountered before. If you know Angular and are attempting to justify its adoption at your company or on your project, this post will offer you with some background data which will facilitate. If you have no idea what Angular is, read on, because why it’s so powerful and then point you to resources that will get you up to speed, quickly.
This post isn’t intended to bash KnockoutJS or coal or Backbone or any of the opposite popular frameworks that you just might already be using and are accustomed to.
1. AngularJS offers XAML Developers a place to travel on the web
Make this bullet a bit “tongue-in-cheek” because the bulk of developers using Angular probably haven’t touched XAML with a 10 foot pole. That’s OK; the reasons why XAML became popular within the Microsoft world through WPF, Silverlight, and currently Windows Store app development area unit necessary to seem at as a result of the translate quite well to Angular. If you’re not familiar with XAML, it's a declarative language based on XML used to instantiate object graphs and set values. You’ll define various types of objects with properties and literally price a collection which will get created. The most common styles of objects to form area unit interface parts like panels and controls that make a show. XAML makes it simple to layout advanced UIs which will change over time. XAML supports inheritance (properties outlined as children of parents will pick up values set higher within the tree) and bubbles events similar to the HTML DOM.
2. AngularJS Gets eliminate Ritual and Ceremony
Have you ever created a text property on a model that you just wish to bind to your UI? However is that worn out varied frameworks? In Angular, this AngularJS Training in Marathahalli may work with none problems and directly reflect what you type within the span:
Of course, you’ll rarely have the luxury of building an app that simple, but it illustrates how easy and simple data-binding is within the Angular world. There’s very little ritual or ceremony involved standing up a model that participates in data-binding. You don’t need to derive from an existing object or expressly declare your properties and dependencies – for the most half, you'll simply pass one thing you already have to Angular and it simply works. That’s very powerful.
3. AngularJS Handles Dependencies
For testing, Angular allows you to divide your app into logical modules that can have dependencies on each other however are initialized separately. This allows you to take a very tactical approach to your tests by delivery in just the modules you're interested in. Then, because dependencies area unit injected, you'll take an existing service like Angular’s $HTTP service and swap it out with the $httpBackend mock for testing. This allows true unit testing that doesn’t place confidence in services to be stood up or browser UI to render, whereas also embracing the ability to form end-to-end tests as well.
4. AngularJS permits Developers to specific UI declaratively and reduce side Effects
There are many advantages to a declarative UI. XAML earlier in this post, but HTML is within the same boat. Having a structured UI makes it easier to grasp and manipulate. Designers who aren’t essentially programmers will learn markup way easier than they'll programming. Using jQuery you finish up having to know a lot concerning the structure of your documents. This creates 2 issues: initial, the result's loads of unstable code operating as “glue” that's tightly coupled to changes within the UI, and second, you finally end up with heaps “magic” as a result of its not evident from observance the markup merely what the UI will do. In different words, you will have tons of behaviors and animations that are wired up “behind the scenes” thus it’s not apparent from gazing the form tags that any validation or transitions are happening.
5. AngularJS allows Massively Parallel Development.
One of the largest problems we encountered early in the project was developers stepping on every other’s toes. A part of this is simply a discipline, and even with raw JavaScript you'll follow patterns that build it additional modular, but Angular simply took it to a different level. That’s Angular Training in Marathahalli with placement to not say it fully eliminates dependencies, however it definitely makes them easier to manage. As a selected case in purpose, there's a vast grid within the application that's used to drive many key operations. During a traditional JavaScript application it may is a merge nightmare to scale this across a large team. With Angular, however, it was simple to interrupt down the various actions into their own services and sub-controllers that developers may independently take a look at and code while not crashing into one another as typically.
6. AngularJS gives Developers Controls.
One of the foremost common complaints concerning moving to MVC was “what will we do with all of these controls?” the first perception was that controls don’t work/wouldn’t operate within the non-ASP.NET space, but internet developers who use alternative platforms know that’s simply not the case. There are a variety of how to embrace reusable code on the online, from the thought of jQuery plugins to third-party control vendors like one in all my favorites, KendoUI.
Angular enables a new scenario known as a “directive” that enables you to form new HTML parts and attributes. Within the earlier example, the directive for the “data-ng-model” allowed data-binding to take place.
7. AngularJS Supports Single Page Applications.
In case you missed it, this time continues the last one. Single Page Applications are becoming additional popular for a good reason. They fill a really specific want. Additional functionality is being moved to the online, and the browser is finally realizing its potential as a distributed computing node. By design, SPA applications are much more responsive (even although a number of that's perception). They’ll offer an expertise that feels nearly sort of a native app within the web. By rendering on the client they abate load on the server likewise as cut back network traffic – rather than causation a page of markup, you'll send a payload of data and switch it into markup at the client.
