- Fast compilation and execution speeds.
- Strongly typed but also supports dynamic programming.
- Web applications can be built using Dart (Dart-to-JavaScript compilation).
Primary Use Cases:
- Cross-platform mobile apps (Flutter)
- Web applications
- Backend development (via Dart’s backend framework, Aqueduct)
5. Kotlin – The Official Android Language
Kotlin continues to dominate Android app development since Google declared it the preferred language for Android in 2019. In 2025, it’s expanding into other domains like server-side development and web applications.
Why Kotlin?
- Fully interoperable with Java.
- Reduces boilerplate code, increasing development efficiency.
- Supports functional and object-oriented programming.
- Officially supported by Google for Android development.
Primary Use Cases:
- Android app development
- Web development (Kotlin/JS)
- Server-side applications (Ktor framework)
6. Swift – The Best Language for Apple Ecosystem
Swift has been Apple’s preferred language for iOS and macOS development since 2014. Its modern syntax, safety features, and performance improvements make it a strong competitor for mobile development.
Why Swift?
- Fast execution speed compared to Objective-C.
- Safe and modern syntax, reducing runtime errors.
- Expanding into server-side applications.
- Open-source with active community support.
Primary Use Cases:
- iOS and macOS applications
- Server-side development (Swift on the server)
- Embedded systems and IoT
7. TypeScript – JavaScript with Superpowers
TypeScript is JavaScript’s superset that adds static typing, making web development more robust and scalable. It is increasingly adopted for frontend and backend development.
Why TypeScript?
- Helps catch errors early through static typing.
- Enhances maintainability for large-scale projects.
- Fully compatible with JavaScript.
- Supported by major frameworks like Angular, React, and Vue.js.
Primary Use Cases:
- Large-scale web applications
- Enterprise-level frontend development
- Backend development (Node.js with TypeScript)
8. Elixir – The Powerhouse for Real-Time Applications
Elixir, built on the Erlang VM, excels in handling concurrent, distributed, and fault-tolerant applications. It’s a top choice for scalable real-time systems like chat applications and IoT platforms.
Why Elixir?
- Highly concurrent and distributed.
- Fault tolerance ensures system stability.
- Used by companies like Discord, Pinterest, and WhatsApp.
Primary Use Cases:
- Real-time chat applications
- IoT platforms
- Scalable web applications
9. Crystal – Fast and Elegant Like Ruby
Crystal is an emerging language that brings the elegance of Ruby with the speed of compiled languages like C. It’s gaining traction for web development and system programming.
Why Crystal?
- Ruby-like syntax with performance close to C.
- Type inference without explicit type declarations.
- Suitable for high-performance applications.
Primary Use Cases:
- Web development
- System programming
- Command-line tools
10. Zig – A Strong Alternative to C
Zig is a relatively new language focusing on safety, performance, and minimalism, making it a strong alternative to C and C++.
