The popularity of programming languages can be influenced by various factors, including their overall utility, familiarity to developers and employers, and standing in software development's ever-shifting landscape. New Relic takes an annual survey to analyze measures of programming language usage and identify trends in the industry. Established languages like Java and Python remain popular, but there are ongoing debates about what constitutes a programming language and how to define a methodology for ranking them. The industry is shifting towards microservices and containerization, with polyglot programming becoming more prevalent as companies adopt a multilingual approach to create small teams that can work independently. Microsoft's .NET Core framework has gained traction, potentially altering the relative popularity of key languages. Employers' requests for specific languages are often used as an indicator of their popularity, but there is some variation in these lists. Python appears to be gaining momentum, with its rise attributed to its straightforward syntax and flexibility. Other languages like Go, Elixir, and Julia are also gaining traction, with Go being a notable example due to its ease of use for networked applications and potential growth in cloud and serverless use cases. Ultimately, the popularity of programming languages can be complex and influenced by various factors, making it essential to stay up-to-date on emerging trends and technologies.
