This report presents the combined results of the fifth annual Developer Ecosystem Survey conducted by JetBrains. 31,743 developers from 183 countries or regions helped us map the landscape of the developer community.
Here you can find the latest trends in the tech industry, as well as interesting facts about tools, technologies, programming languages, and many other facets of the programming world.
