Growth Hacking: How it differ from Traditional Hacking


Hello this is Gulshan Negi
I am a software developer. Well, I don’t know much more about growth hacking; however, I am familiar with both traditional and digital marketing. I have a concern: how do you differ it from traditional marketing, is growth hacking better than traditional marketing? If yes, then how do I get started with growth hacking?
I need some suggestions on this.
