5. Ruby
Ruby is known for its elegant syntax, which is easy to read and write, making it a favorite for web developers, particularly those working with Ruby on Rails. It emphasizes simplicity and productivity, allowing developers to create applications quickly and with fewer lines of code. Ruby is ideal for startups and small businesses looking to build web applications efficiently.
Popular framework: Ruby on Rails (web development)
6. Swift
Swift is Apple’s programming language for developing iOS and macOS applications. It has been rapidly growing in popularity due to its modern features, safety, and high performance. Swift is an essential language for anyone looking to build mobile apps for Apple devices, and it offers a great alternative to Objective-C, Apple’s previous language.
Popular use cases: iOS apps, macOS apps, Apple Watch apps
7. Go (Golang)
Go, also known as Golang, was developed by Google and is known for its simplicity, efficiency, and scalability. It’s an excellent language for building high-performance systems, cloud computing applications, and distributed systems. Go is a go-to choice for backend development, microservices, and large-scale infrastructure projects.
Popular use cases: Cloud services, distributed systems, server-side applications
8. PHP
Despite facing some criticism, PHP remains one of the most widely-used languages for server-side web development. It is used in a majority of websites and web applications, especially when combined with databases like MySQL. PHP is easy to learn for beginners and is a great language for creating dynamic web pages and applications.
Popular frameworks: Laravel (web development), WordPress (content management system)
9. TypeScript
TypeScript is a superset of JavaScript, adding static typing to the language. It has been gaining traction in recent years, especially for large-scale applications that require maintainability and scalability. TypeScript is particularly useful for developers working on complex, data-driven web applications and is often used with modern JavaScript frameworks like Angular and React.
Popular frameworks: Angular (web development), React (UI development)
10. R
R is a programming language specifically designed for statistical computing and data analysis. It’s widely used by data scientists, statisticians, and researchers for data visualization, statistical modeling, and machine learning. If you’re looking to specialize in data science or data analytics, learning R will give you a competitive edge in the field.
Popular use cases: Data analysis, statistical modeling, machine learning
How to Choose the Best Coding Language for You
Choosing the best coding language depends on your career goals, the projects you want to work on, and the industries you’re targeting. Here are some tips to help guide your decision:
- If you want to build websites: JavaScript, HTML, and CSS are essential. If you want to specialize in backend development, consider learning Node.js, Ruby, or PHP.
- If you’re interested in mobile app development: Learn Swift for iOS apps and Kotlin for Android apps. Alternatively, you can explore cross-platform development with JavaScript frameworks like React Native.
- If you’re aiming for data science or machine learning: Python and R are the most popular languages. Python’s libraries like TensorFlow and Pandas make it especially powerful for these fields.
- If you want to work with enterprise systems: Java and C# are widely used for large-scale enterprise applications and backend systems.
Conclusion
The best coding languages to learn in 2025 vary depending on your specific interests and career aspirations.
