Learning Paths

With so many tutorials, articles and resources available out there on the Internet, learning new programming language, framework and library become much more easier. However, as much as its advantage, readily available resources have also become its own problem: where should I start?

With so many options available, it can be confusing to even start learning. I present you my learning paths to solve this problem. Learning paths will guide you through learning programs for each subject of your interests. Think of this as a curriculum to the degree you want to get.

Most of the courses are from Pluralsight.com, but this learning paths are not limited to just Pluralsight.com. I also include some free courses from other sources. While I understand that you may have to pay for some of these courses, I can assure you that paying the subscription is worth it (especially Pluralsight!).

I will update this learning paths to include more subjects and courses in the future. Stay tuned!
