He believes strongly that deeply understanding any topic allows you to properly learn it and, even more importantly in a real-world environment, quickly overcome problems.

The model used to retrieve data requires a series of callbacks and checking of status codes, as well as managing the parsing or processing of the response data to get it into a usable format. As developers struggled to build applications that worked across browsers using the various APIs available, Resig created jQuery as a way to simplify selecting DOM elements. Once selected, elements could easily be manipulated, have event handlers attached, or be removed completely from the document. As developers tested this in their applications and gave feedback, the library improved and is now a default option in many applications. In fact, many other libraries and frameworks now depend on jQuery rather than rewriting the functionality it provides. Frameworks provide a set of constructs for building your application, while libraries are sets of useful functionality encapsulated in one or more JavaScript files – and there’s no shortage of either.

The Angular 2 Component combines the AngularJS Directive, Controller, and Scope. My article will attempt to make you more comfortable with components by comparing them to what you already know from AngularJS.

Unlike other frameworks, there is no need to inherit from proprietary types in order to wrap the model in accessors methods. This makes your code easy to test, maintain, reuse, and again free from boilerplate. AngularJS is a toolset for building the framework most suited to your application development. Every feature can be modified or replaced to suit your unique development workflow and feature needs. HTML is great for declaring static documents, but it falters when we try to use it for declaring dynamic views in web-applications.

Creating an AngularJS module

It should be simple to get through if you have a basic understanding of JavaScript. For the average learner, it takes less time to learn the components of React than to learn what AngularJS has to offer. So long as you have a basic understanding of JavaScript, you should be fine.

A $scope is a JavaScript object which is used for communication between controller and view. Basically, $scope binds a view to the viewmodel and functions defined in a controller. A component allows you to hide complex DOM structure, CSS, and behavior. This lets you focus either on what the application does or how the application looks separately. Components also define the styles attribute where directives do not. They do not “leak” to elements in the outer HTML or to other Components.

Round trip apps get this automatically, but AJAX apps by their nature do not. AngularJS combines the benefits of deep linking with desktop app-like behavior. He also has a deep interest in human nature and behavior, and how that impacts human-computer interaction.
