October Highlights

Postings in October's "Ask HN: Who is Hiring" thread were up over 12% from September as fall hiring kicked into high gear. In fact, this was the 2nd highest posting month of all time, behind only this past Februrary. In previous years, November usually surpasses October, so it will be worth watching next week to see if hiring can remain hot.

React took the top spot for the fifth straight month, approaching 25% of all postings and opening up a larger lead over Python. The top 10 only saw a little shuffling with Node.js re-entering the Top 5 for the first time since January and Docker sliding down to #13. Ruby swapped with Docker with a jump to #10.
