Angular JS vs. Angular 2- The choice is clear

Angular JS was introduced in 2009 and since then it has been a reliable and popular framework for creating Single page web application. As a JavaScript web framework, it was created with test-ability in mind with latest in-built features like Separation of Concerns and Dependency Injection as a part of its framework. With such useful features in place, Angular JS was an instant hit with enterprises who were keen on reducing development costs while keeping the delivery time to a minimum.

As a professional provider of customized web development services. we made extensive use of this framework to give our clients the best of both, costs and delivery. Just when designers thought it couldn’t get better, Google introduced Angular 2 in 2014 in a completely refreshed and refurbished avatar, with JS being dropped from its name since JavaScript was now replaced by Typescript as its preferred dialect.

So what has improved?
• Angular 2 has been endowed with a better separation between Angular characteristics and Standard HTML.
• The HTML5 compliant data-ng-click and ng-click has been swapped with (click) attribute with parentheses around it which indicates DOM changing attributes and one-way vs. two-way data binding.
• Angular 2 has a much tighter integration with Typescript, thus ensuring a more resounding performance this time around.
• For a faster checking of a one-way binding, the $scope.digest cycle has been replaced with a simple and direct Javascript logic.

All said, Angular 2 has its own disadvantages as the now familiar concepts of $scope, directive and watch. With the addition of Typescript and Dart, many JavaScript developers miss the familiarity and ease of use. As a top ranking web development company in Mumbai, we realise that while there isn’t an emergency about migrating to Angular 2, it would certainly become a preferred choice for new and upcoming projects being launched.
