At the moment, the TIOBE index monitors . 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. 265 popular programming languages However, there are many more technologies that are in current use or have already fallen off the radar. Wikipedia tracks with the view of involving all notable technologies in existence. So, how do you pick the best one to build a software project? over 700 programming languages 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. Top 8 programming languages for 2020 and beyond Programming language popularity (2015-2019) by Stack Overflow survey Python supports multiple programming paradigms that involve object-oriented, procedural, and functional programming. The core philosophy behind Python is based on simplicity and high code readability. 1. Python As StackOverflow reports, Python is the 4th most used and the second most loved programming language among software engineers from all over the world. YouTube, Instagram, Dropbox, Reddit, Quora, Spotify, Netflix, and many other globally known projects are implemented with the help of Python.

JavaScript StackOverflow Developer Survey 2019 Today many world-famous companies like IBM, Linkedin, Uber, PayPal, and Walmart are already using JavaScript to build their digital products. Netflix, an American production company and one of the largest online media streaming providers in the world, leveraged Node.js to redesign its platform. Representing a cross-platform JS runtime environment, Node.js executes JavaScript code outside of a browser. This technology lets programmers employ JavaScript for server-side development. Node.js is widely used for making scalable software solutions. Previously, Netflix had the server-side created in Java and front-end built with JavaScript. As a result, engineers had to know both languages to be able to write the code twice. This prolonged the app development and deployment processes, as well as required additional efforts from the team. Developers who had already had experience in JavaScript transferred the server-side to Node.js. “We have improved performance and reduced infrastructure costs with Node. We now are serving the same number of subscribers at lower latencies,” — , Principle Engineer at Netflix, in his interview about using Node.js. said Yunong Xiao “The dynamic nature has enabled us to rapidly develop, test, build and deploy presentation layer and server-side code, including templates and client-side assets,” —he added. The main use cases of JS are: Web development Mobile application development Backend development Serverless computing Browser solution development Thus, JavaScript is a successful choice if you need to produce a scalable and high-performance solution. Being capable to run almost everywhere, this language perfectly suits for designing dynamic applications and modern user interfaces with various interactive elements. TypeScript closes the top ten most popular programming languages on StackOverflow Developer Survey conducted in 2019. It is also the world’s third most loved language among software developers. 4. TypeScript Representing a strict syntactical JS superset, this open-source language adds optional static typing to JavaScript and compiles to plain JavaScript. TypeScript enables engineers to employ JS code, incorporate JS libraries, and call TypeScript code from JavaScript. Created and maintained by Microsoft, TypeScript can be run on any browser, host, and operating system. Supporting a wide range of tools, it’s a perfect match for making large-scale solutions and complex web interfaces. TypeScript has the same use cases as JavaScript. “In our , we enjoy TypeScript for its rich functionality, strong community support, and expressiveness. Compared to other technologies, TypeScript enables programmers to ensure higher, reliability, scalability, and easier maintenance as well.” custom mobile and web development company Sergey Glebko, Co-founder and CTO at Arateg Being a general-purpose scripting language, PHP is mainly used for web development.
