Getting Started with Angular 2 step by step : Your First Component
Why Should You Care?
The JavaScript and web world has changed a great deal since Angular JS was discharged. Angular 2 takes favorable circumstances of the considerable number of advances that have occurred from that point forward, grasps web norms and gets rid of a ton of develops that are currently local to Javascript, for example, modules,classes or decorators.
And not only that,it draws on all the teachings of tons of projects carried out by thousands of developers in AngularJS to provide a more consistent and compact developer experience.One with a reduced number of concepts to grasp and an easy-to-learn development model and syntax.
It is also faster,provides server-side rendering out of the box,is cross-platform,supports legacy browsers. etc
Angular 2 is the regular way ahead for all the AngularJS engineers out there and an incredible decision for those that welcome a stubborn system with a reasonable arrangement of defaults,focus on measured quality and testability.
Is Angular 2 Ready?
Angular 2 is ready indeed! since the initial publishing of this article Angular 2 has gone from beta, to RC, to final and now it is in its version 4.It is used not only by numerous companies but even extensive lt at Google in more than 200 projects including AdWords,GreenTea (Google's internal CRM system), Google Fiber and Google Cloud Platform.
The Code Samples
You can download the complete code samples for this blog post from this GitHub repo. You can likewise check the incredibly cool online supervisor Stackblitz which has wonderful suppoprt for composing Angular models on the web.My recommendation is that you follow the tutorial along using your own development environment,that way you get to enjoy the full Angular developer experience.But if you do not have time or energy to set it up right now, then try Stackblitz.
Getting Started with Angular 2 and Typescipt
The most ideal approach to begin learning Angular 2 and Typescript is to utilize the Angular CLI to bootstrap another task.
The Angular CLI is incredible in light of the fact that it incorporates all that you have to begin composing your Angular 2 application immediately: Afront-end fabricate pipeline to traspile your TypeScript into JavaScript that can keep running in the browser,lots of generators to platform your application, a web advancement server that naturally mirrors your adjustments in the programs as you make them and much more.I call that zero-grinding learning.
So start by installing the Angular CLI using npm ( you will need to install node.js and npm in your development machine before you can continue).In your terminal of chioce type :

PS> npm install -g @angular/cli
Presently you are prepared to utilize the Angular CLI to make another project.The direction that you use to get to the Angular CLI is ng.To make another application type the accompanying.
PS> ng new angular-get-started --style scss
This will make another Angular 2 venture sans preparation and set it up with the goal that you can utilize SASS as CSS preprocessor.If you go inside the angular-get-started folder that should have just been created you will find a folder structure that will look more or less like this :
// app source code (and specs)
-app # your app source code (and specs)
-assets # static assets like images, etc.
-index.html # the entry point to your app
-styles,scss # the global styles for your app
-environments #here you can define different environment configuration (prod,dev, etc).
- node_modules# the source code of your app's dependencies
- package.json# the manifest of your app that states all dependencies
//TypeScript configuration
-tsconfig,json # TypeScript compiler configuration
-tslint.json # TypeScript linting configuration
-e2e #a folder with end to end tests
-karma.conf.js #karma test runner configuration
-protractor.conf.js # protractor e2e tests configuration
- .gitignore
You can test everything works as it should by running the development server.Type the following command.
PS> ng serve --open
# the short-hand syntax is : ng s -o

This should start the development server,open a browser and load your app.You can stop the server any time by typing CTRL-C a couple of times in the terminal.But for the time being just rejoice!You have created your first Angular 2 application!
The index.html is the entry point to your application.
*It links to yours styles and javascript files
*It provides the HTML markup for your application with the custom element.

The enormous thought behind React is making your own components like HTML elements.In React,a page is an accumulation of littler pieces,these little pieces are called parts.Developers can utilise these components to efficiently create large web applications,which can change the displayed elements or data without the need to reload the page.a simple example of this would be Facebook likes.The number of likes can increase or decrease without having to reload the page.This method has made it very easy to build modern,complex user interfaces. Evolution of React In 2011,Facebook developers started to face some issues with code maintenance.As the Facebook Ads app started growing exponentially,the team needed more people to keep it running perfectly.over time,their app became difficult to handle,as they faced a lot of updates.Their code demanded an urgent upgrade to become more efficient.
