I have been a Python developer, working for around 4 years now. Though I learned C, C++ and Java in my college I never took any of them seriously as there were not enough jobs in the market for these languages. Also Python was a lot easier to get started. I know JavaScript enough to make a simple functional website.
I am thinking of learning a new language and try building something. What
would be a great second language to learn?
ReactJS and Tailwind CSS
I would learn more JS and start using React.
But I actually believe in just in time learning.
So start building something and learn the skills you need for it.
I do know JS, have done few works using NodeJS. My front end is not so good, I prefer using Vanilla JS over React/Vue but I am thinking of diving into Vue soon.
