So I have been reading this post:

JavaScript Is Eating The World

Anthony Delgado ・ Aug 24 '17

#node #javascript

and I have been practicing through freecodecamp as well and I came to know that React.js comes under their data Visualization section so I was wondering what is it? and why React.js and other front end stuff comes under that.

I bachelors in ICT (basically CS) and always practiced Data Structures and Algorithms on online judges or otherwise and have been creating simple web apps like blogs and weather app with Python Django and then also with Node.js express.js

( I know I should have started with React.js/Vue.js/Angular in short with front end but I didn't is it bad? what should I do? for job perspective in mind)

I had a Data Mining Course in my junior year at college but I don't know much about how these front end technologies comes under Data Visualization.

Any explanation/advice/guidance will help
