Hey Joshua,
I'm hoping for a necromancer badge for this one, answering 5 years after you asked
React is one of the best bets for a scalable, production ready front end framework.
I was also curious what companies are using it and hiring for it.
I live in the Bay Area and collected a list of companies that use React. I combed through job listings, who has hosted meetups etc
Here's a map and list of companies in the Bay Area currently using React.js: employbl.com/blog/companies-that-use-reactjs-in-b… (over 100 listed, from startups to enterprise)
I hope other React devs find this post useful
