Angular

Angular

  • Angular is a structural framework for building dynamic web apps. With Angular designers can use HTML as the template language and it allows for the extension of HTML's syntax to convey the application's components effortlessly. Angular has components and those components are highly reusable in the Angular application.
  • Angular is a cross platform language. It supports multiple platforms. You can build different types of apps by using Angular.Those application are Desktop applications, Native applications, Progressive web applications.
  • Angular provides Testing, animation and Accessibility. It provides full stack development along with Node.js, Express.js, and MongoDB.

Special Characteristics of Angular

  1. MVC –  This is a design pattern used in all modern day web applications.
  2. Data Model Binding – You don’t need to write special code to bind data to the HTML controls. This can be done by Angular by just adding a few snippets of code.
  3. Writing less code
  4. Unit Testing ready – The designers at Google not only developed Angular but also developed a testing framework called “Karma” which helps in designing unit tests for AngularJS applications.

 Advantages of using Angular

  • Two-way data binding
  • DOM manipulation
  • Improved server performance
  • Faster application prototyping
  • Responsive web
  • Highly testable products
  • The MVVM architecture
  • Use of directives.
  • The Plain HTML templates

Disadvantages of using Angular

  • JavaScript support mandatory
  • Inexperience with MVC
  • Other difficult features
  • Possible time consumption


  • AngularJS is a one of  JavaScript framework. It can be included to an HTML page by using <script> tag.

         <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>


  • AngularJS extends HTML with ng-directives.


  1. The ng-app directive defines an AngularJS application.
  2. The ng-model directive binds the value of HTML controls (input, select, textarea) to application data.
  3. The ng-bind directive binds application data to the HTML view.
  4. The ng-init directive initializes AngularJS application variables.


          Eg : <div data-ng-app="" data-ng-init="firstName='John'">

                  <p>The name is <span data-ng-bind="firstName"></span></p>



  • AngularJS expressions are written inside double braces: {{ expression }}.

Angular 6 - Data Binding Part 2

Image
 Data Binding - 2 Event Binding Event binding used to build interactive angular applications with the flow of data from component to the element and from element to component . Event binding syntax will have a target event name within parentheses on the left of an equal sign, and a quoted template statement on the right. Eg 1: In this example I used a button to demonstrate the event binding. In here we are binding an onClick() event to the button element. When the user clicks on the button, event binding listens to the button's click event and calls the component's onClick() method in component.ts file. Eg:2  . In here there is  a method named "onUpdateServerName" and add an event with it.

Machine Learning  What is  Machine Learning? "Machine learning is the scientific study of algorithms and statistical models that computer systems use to effectively perform a specific task without using explicit instructions, relying on patterns and inference instead. It is seen as a subset of artificial intelligence." In traditional programming, we feed a set of instructions for a defined set of scenarios to the computer. Then the computer will utilize its computing capabilities to help human process the data efficiently. In machine learning, a large amount of data is input into the computer. Then computer processes all the data and comes up with a trained model(solution). After this model is used to solve the unseen problems of the real world. Applications of  Machine Learning Machine Learning has started growing fast because nowadays we have less expensive computational power and lots of data which we can use the train our models.
