Get SSD to have speed. I replace my 6 years old HDD with SDD. It is 3 times faster for Android development studio. Especially build time where smaller size files are copied. Even copy of big files are three time faster in my machine. It still use my old HDD for backing up files which I rarely uses.

If you are beginner who just learned css, html, javascript, my advise is not to learn framework right after that. It would be good if you master them before learning frameworks, frameworks are build on the basics. For learning anything, mastering basics is very important from my perspective.

Thanks for the reply and tip. I have modified the question and added extra part into body. Your example is clear and I understand little bit. I will explore more.
