Pros:

• An open source framework, so this is literally free!!
• Built-in with HTML 5 which is really a light and easy to manage.
• It has a lot of developers already who uses the framework, so I could say a very legit thing!!
• It is very easy to setup! Yayy

Cons:

• No cons at the moment since this is for free!!

Congrats for this hunt! Great job!!
