December 2019 Hacker News Hiring Trends
Just as it did last year, React completed the full calendar 2019 as the top tech in Ask HN: Who is hiring? extending its win streak to 31 months. React has been trending down in recent months and December marks its lowest share of the year, at just over 25% of postings. But, the runner up, Python, still has a long way to go to catch up.
There were some notable big movers in December. Machine Learning made a jump from #12 to #4. While Go jumped back into the Top 10 overall and was the second most popular programming language.
The other big story for 2019 would have to be TypeScript which is now a Top 10 contender every month and at parity with JavaScript regularly.
