Introduction of Angular 4

From the title of the article itself, as a tech geek, you may be worried about similar experience between transformation from Angular 1 to Angular 2.
But don’t worry, this time it’s more of a version number change, with some new features rather than a complete framework level change like what we saw with the transition form Angular 1 to Angular 2. This release is backward compatible with 2.x.x for most applications.
