Thanks j . But if someone is not PHP then he might face challenge to understand the doc well. In such case nice and step-by-step guideline would be helpful. I purchased some multipurpose themes from themeforest but code was not upto the mark. So just to develop anyone can do by following docs but to develop in such manner that can be sellable, we should stick to the standard approach that is what I believe personally :)

Even I am new to WP headless approach. But I tried to create little demo by setting up WP instance to be consumed by Angular app. And up to now all went awesome and still it's on. Lot of learning... Soon planning to launch blog series on my personal blog :)

I came across one blog which is built on React: https://ponyfoo.com/. I wondered, how they guys manage SEO thing???

I love Github for 2 reasons. It's open for other contributors and even non-contributor can see the code as everything is public on Github for FREE account. I love Jekyll. However it can be configured on Bitbucket, I personally more comfortable with Github Pages :) Thanks.

Good thought but usually prominent libraries use the most easiest keywords for developers :)

This question is not about what people follow. This is about the mentality. Developers from India doesn't care much for the community, they only care for client and the project. I am also from India and this is my personal experience. I have met many developers in big companies with great years of experience but cannot explain the latest technology. They use to stick with traditional techs only.

:) In reality, you will find very less developers contributing to open source from India. I don't know the reason but they are satisfied with their 8 hours job. Don't care to learn new thing.
