On 27th Aug, I hosted second event of my Angular 2 Road Trip in Gurgaon.. Read more about AngularJS 2.0 here . This time, it was turn of city Gurgaon to show the love for Angular 2  and there were around 280-300 developers attended the event.

You might be wondering that why people are seating on the floor? because I had more attendees than expected. I thought there would be maximum 100- 130 people would join the event. But I was wrong, and around 300 people attended the event. There were no enough chairs for all 300 people, so we removed all the chairs from the hall such that everyone could be accommodated by seating on the floor. I must appreciate passion and learning attitude of each participants that they agreed to seat on the floor for 5-6 hrs. We all sat on the floor for the learning and love of AngularJS 2.0

image

In six hours I covered following topics,

  • Setting up development environment in VS Code
  • Understanding Bootstrapping
  • Understanding Modules
  • Understanding Components
  • Creating first component
  • Creating Service
  • Understanding Routing
  • Performing CRUD operations using http

I also covered basics of JavaScript functions, objects, and inheritance. Attendees were very much involved and fully participated. I used Dan Wahlin AngularJS 2.0 project from GitHub as the starter project and built application on top of that.

image

I was very motivated and aspired to do better seeing participations and passions of people, even though they were seating on the floor for whole days and many of them did not get lunch. I must each attendee for their support in successfully execution of the event.

image

I must also thank Microsoft India, specially Usha Rathnavel for her support in providing us hall, coffee/tea and lunch for the attendees on very short notice. Without her help this event was not possible.

image

Once again I thank each developer who came for the event. Since I am based out of Delhi, aspired to so more such event in Delhi.

image

Last but not least I would like to thank below mentioned people for their support in making AngularJS 2.0 multi city tour success.

Brad Green, Dan Wahlin, Geard Sans, Jaosn Beres , Todd Motto , Glenn Block

What are Closures in JavaScript?

Read full article on the Infragistics Blog

A JavaScript closure is a function which remembers the environment in which it was created. We can think of it as an object with one method and private variables. JavaScript closures are a special kind of object which contains the function and the local scope of the function with all the variables (environment) when the closure was created.

image

To understand closures, first we need to understand SCOPING in the JavaScript. We can create a variable or a function in three levels of scoping,

  1. Global Scope
  2. Function or local scope
  3. Lexical scope

I have written in details about scoping here, but let’s take a brief walkthrough of scoping before getting into closures.

Scopes in JavaScript

As soon as we create a variable, it is in a Global Scope. So, if we have created a variable which is not inside any function, it is in a global scope.
