Hi Sakthivel,
This is basically how objects are instantiated, not views specifically. It is JavaScript syntax.
I'd suggest you spend some time looking at JavaScript syntax before diving into some of the SAPUI5 content, to get a good background on how to write it, understand it and run it.
I find the courses on Codecadamy are a great place to learn as they are free, short lessons that you can work through when you have a spare 10mins and help build up good understanding of the basics.
Hope this helps,
Gareth.
