Does it matter which country I am in to pursue this dive?
The best news about studying Node is that no matter where you are in the world, you can quite easily improve your Node skills. As long as you have access to a laptop, you will be able to practice your skills, improving every day.
The bottom line, the answer is no: it doesn't matter at all which country you are in. Wherever you are, you can start learning or improve your Node skills. Truly, these days, if you want to become fluent in Node.js, and you aren't currently fluent, the only reason is: "YOU ARE LAZY".
