The most popular programming languages aren't always the same ones as those that are in demand. And those that are in demand are different in different parts of the world.

These findings come from Hired, a company that sets out to match coders with jobs. Its marketplace consists of over 10,000 companies and millions of job seekers and its 2019 State of Software Engineers is its first initiative to share its data about hiring trends - both the hottest jobs and the hottest coding languages. 

The report presents an analysis of proprietary information collected by Hired's data science team from interview requests, job offers and other sources. It also relies on responses from more than 700 software engineers form 13 cities.

The top finding from the survey is that demand for blockchain engineers is up 517 percent year on year and for security engineers it is up by 132 percent:

When it comes to programming languages, JavaScript (62%) was the most widely used by Hired's developers, followed by Java and Python (42%), then HTML (36%):

Despite the fact that only 7% worked with it, Go is the language with the greatest number of interview requests on a global basis:

In fact, there was a lot of local variation in the most in-demand programming language. While Go is the clear winner in Paris, Typescript occupies the top slot in San Francisco Bay Area, Toronto and London, although not by much as Go, Scala, and Ruby are all close behind. And in New York Ruby emerges as most-demanded. The report concludes that no one likes R; it is consistently the least in-demand language across markets.

The report also gives insights into the most and least popular programming languages:

It comes as no surprise that Python is the most popular language with just over half of respondents nominating it. JavaScript is almost as popular, with Java and HTML also loved by over a third of developers.  PHP is the most unpopular - although only 1 in 5 put it in that position. Java and Objective-C were also disliked by over 1 in 10 devs.

Other takeaways from the survey are:

• 1 in 5 software engineers are self-taught
  
  
• Half of engineers prefer to work at a company that does pair programming
  
  
• 43 percent of developers prefer to work for companies that contribute to open source projects
