Adding a new product to $scope

$scope helps the controller passes data to the view.  We are storing an object of key value pairs into the $scope.product variable. Single word keys like name and price don't need quotation marks, but regardless of the length and construct of the string, quotes are needed when storing values hence the book name is surrounded by quotes. However, we don't need quotes when storing numbers, hence 19 doesn't have quotes around.

Displaying book title and price

If we just write product.name nothing will happen. HTML will literally display things exactly how it is. Because when the words are surrounded by double curly braces {{ }} AngularJS is smart enough to know to take a look. Rather than display as it is, it will traverse upward in the HTML code to see where it should be looking for useful data. It found that somewhere upward, it is told to look at the MainController, so it checks if there's a product property or variable stored in the $scope object. Found! Then it checks if there's .name and .price property. Found! AngularJS is able to successfully display the data. If we change the data now to {name : "My book", price: 25}. We no longer have to change HTML code. It was a one time setup. This time when running the code, AngularJS will again look for $scope.product.name and $scope.product.price but will find different values to display.

Some of these 146 companies are familiar like Pinterest, Lyft and Facebook. Some are unicorns with a foreign passport : Xiaomi, Kuaidi Dache (Chinese Uber). Some are straight out unheard of such as CureVac founded in Tubingen Germany making vaccines.

One thing for sure, these are no longer startups though they all have humble origins. They are shiny unicorns of massive valuations i.e. potentials of generating revenue. Some already do.

Silicon Valley Startup & Technology News January 2016 Parse Women Who Code Airbnb IPO

Data as a Service Facebook Parse Shutting Down : just a few hours ago, Parse Blog announced the shutdown. Parse is now officially in "sunset period" until January 28 next year. It released a new database migration tool and an open source server code Parse Server (available on Github), which will allow developers to run Parse like structure on Node.js server.

Airbnb IPO? There are rumors on smaller stock investing websites pointing Airbnb out as the best candidates for 2016 IPO. We became familiar with Apple product rumors to be partly true. They may be true leaks, marketing stunts, or just testing the water. The ending almost always has a twist. Airbnb raised money in December 2015, but has not admitted to intention of 2016 IPO. Other notable incumbents include Uber, Palantir, and Xiaomi, all extremely large private Unicorn "startup" clubs.
