A modern programming language that makes developers happier.

kotlinlang

`Day4`
• Introduction of Design Pattern
• Dive down into definition, usecase, implementation of Creational Pattern (Singleton, Builder, Factory, Dependency Injection)
`Self-Comment`
• Gather some learning resources from Udemy, Mindorks blog, and Github. 
• Not much code today, since involves many reading and understanding concept of each pattern.
• It takes quite some time for summarizing even Creational pattern alone, i was planning to finish all patterns in one day but it’s not possible lol.
`Goals Tomorrow`
• Will use this week’s `pass` for tomorrow, got some office stuffs that i need to work on for next Monday. 
• If i have spare time will continue on behavioral pattern. :blob-hype:

Might be a lot to take in if you aren't familiar with Android/MVVM,  but this gives a pretty good understanding of Dependency Injection. Was actually just going over it myself!

Nice article, Bryan! Actually pretty familiar with DI myself since i’m using Dagger 2 in my app. Basically the basic concept of DI is injecting an object to our needed class.
