WarsawJS Workshop #20. Basics of React.js

React.js, a base for single-page applications, surely has potential. Interestingly, ReactJS is maintained by Facebook. So, what have we learnt and is ReactJS worth it?

Other than React, this edition of WarsawJS will be forever remembered for its delicious cuisine. So, what was the food like at Workshop #20?

WarsawJS 20 sponsor SoftwarePlant

Piotr Kowalski, a WarsawJS organizer. SoftwarePlant was a sponsor of Workshop #20. Can you tell the technologies we use?


We’ve heard various rationales from people who spent the Sunday coding in React JS:

  • It’s similar to JavaScript, one could get a grasp of React in a few hours (given proficiency in JS) 
  • React is “loved” compared to Node.js, Spark, Angular and others
  • React is open-source
  • It’s a Facebook technology. Big names utilize it, e.g. Instagram, Netflix, PayPal, Apple
