Take care of tech, so you can focus on core business.
At the moment, the TIOBE index monitors 265 popular programming languages. The TIOBE includes a language on the list if it matches three key requirements: it is Turing complete, has its own Wikipedia page, and provides more than 5,000 search results on Google.
However, there are many more technologies that are in current use or have already fallen off the radar. Wikipedia tracks over 700 programming languages with the view of involving all notable technologies in existence. So, how do you pick the best one to build a software project?
The decision depends on many factors, for instance, the product type (web, iOS, Android), solution category (machine learning, blockchain, big data, etc.), business needs (data security, high scalability, performance, resilience, etc.), other specifications (e.g., statistical computing, data analysis).
Since it’s rather challenging for business owners to choose a programming language for software development, we’ve prepared this article to help you. Take a look at our top 8 which was created on the basis of multiple surveys, ratings, and our own experience.
