Hello,
Angular.js experienced developer available here :)
We think that Angular is probably the most advanced MVC/MVVM framework available right now. We've worked with many other frameworks and libraries across the years, but none were as powerful or as feature-complete as Angular. The data-binding is probably the most powerful and useful feature. While other frameworks like Knockout also provide similar features, none are as powerful and well-thought.
Beside this, the concept of directives and filters are great to work with, and minimize direct DOM manipulation, making it almost unnecessary.
Controllers are also easy to work with, and the $scope concept, along with inheritance, nested templates, and overall dependency injection are extremely helpful.
We usually use the Brunch build tool for our Angular projects. This helps us with concatenation and minification of scripts, along with SASS/LESS compilation, and allows us to keep our code much more organized.
Testing is also a breeze using Testacular, which can run tests either with Jasmine or Mocha, with real browsers, and with PhantomJS on the server/CI.
Let me know what you think about our expertise.
Best regards,
Alexandra
