The choice of programming languages for a specific project depends not only on its ranking on the PYPL index but also on the technical requirements agreed upon with the client
According to statistics from CodeSubmit, the number of job openings for software developers, data analysts, and testers will increase by 22% annually between 2020 and 2030. The strategic digital transformation of businesses is making IT professionals in high demand year after year.
While some fear that generative AI might replace programmers, others are actively searching for new talents. More and more professionals from related or even different industries are transitioning into IT, choosing various career paths in software development, project management, or design.
The array of professions available in IT today is truly astonishing. Moreover, even within development, there are so many varied specialists that it's surprising in itself. Speaking of which, there are numerous programming languages, each with its own style and purpose.
Python remains the most popular programming language year after year. Its popularity especially soared when major companies like Netflix and Facebook started using it as their primary development tool. Following this trend, many other businesses also transitioned to Python.
Python can be used to solve a vast array of tasks. It facilitates the creation of simple web applications and is heavily used in artificial intelligence. Moreover, the open-source machine learning platform TensorFlow, developed by Google, is also compatible with Python.
Python is well-suited for handling vast amounts of data, significantly simplifying the machine learning process. Focus21 developers employed this programming language in the development of the innovative medical mobile application Xtract One for XLabh Innovations and within the TAS Platform ecosystem.
Java is one of the oldest among today's popular programming languages. It's still actively used in development for DevOps, virtual reality, big data, chatbots, and so on. Moreover, Java is one of the primary languages for Android development.
Java powers software in companies such as Google, Amazon, Spotify, Netflix, Instagram, Uber, Airbnb, and other incredibly popular companies and services. As practice shows, Java, in one form or another, is used by 99% of companies born in the digital era or those that have successfully undergone digital transformation.
PHP is still actively used today. It's a general-purpose scripting language primarily designed for web development, facilitating the creation of interactive and dynamic websites. It can be embedded directly into HTML to write straightforward scripts that extend the capabilities of a web page.
PHP is known to be one of the simplest programming languages to learn and use without deep technical knowledge or development experience. According to W3Techs, approximately 77.4% of websites that use server-side scripting use PHP. However, it's not as commonly chosen for new projects as it used to be.
C++ is an advanced high-level version of the low-level programming language C. On one hand, it is used for building simple applications for many desktop operating systems. On the other hand, it offers the capacity to develop powerful mobile apps.
Today, C++ is highly sought after in video game development, machine learning, and big data processing applications. Software developed in C++ tends to run faster than in any other programming language. Nevertheless, its use isn't always justified.
Swift is a programming language developed by Apple. It boasts a modern and clean syntax, reliability in development, and secure usage. Moreover, it minimizes potential errors that developers might make.
On one side, Swift's popularity suffers due to its limited cross-platform capabilities. However, it's with Swift that you can best harness the unique features of Apple's hardware on devices such as the iPhone, iPad, Mac, Apple Watch, Apple TV, and other company-specific gadgets.
Developers who build Android applications are particularly fond of Kotlin because it's much easier to learn and subsequently use than Java. Moreover, due to its backward compatibility, one part of a project can be written in Kotlin, while another continues using Java.
Kotlin is employed by major companies and services like Google, Amazon, Netflix, Uber, Pinterest, Trello, and others. According to Predict, in 2022 Kotlin was among the top three programming languages that companies planned to migrate their software to in the near future.
In the end, it's crucial to understand that there is no perfect programming language. Some are better suited for specific tasks, while others are less ideal. That's why development tools are individually selected based on the specific technical assignment agreed upon with the client.
