  To implement modern web applications, a new family of JavaScript frameworks
has emerged, using the MVC pattern. Among these frameworks, the most popular
one is AngularJS, which is supported by Google. In spite of its popularity,
there is not a clear knowledge on how AngularJS design and features affect the
development experience of Web applications. Therefore, this paper reports the
results of a survey about AngularJS, including answers from 460 developers. Our
contributions include the identification of the most appreciated features of
AngularJS (e.g., custom interface components, dependency injection, and two-way
data binding) and the most problematic aspects of the framework (e.g.,
performance and implementation of directives).
