Use Angular's array-based approach

[hgd878]

Hello Author,

Thank you for creating and sharing this library.

One of the observation from JS file, you have not used Angular's array-based syntax. It is always a best practice to use array-based syntax while working with Angular. Array-based syntax is more like AMD which most of us are already comfortable with.

It's a request, if you can modify your code and include array-based approach, it would be really helpful.

Thanks & Regards, hgd878
