Key differences between Wren and Kotlin
| Characteristic | Wren | Kotlin |
|---|---|---|
| Syntax | Lightweight, minimalistic, inspired by Lua and Smalltalk; uses braces for blocks and is easy to read. | Modern, concise, and expressive; similar to Java but with type inference and less boilerplate. |
| Paradigm | Primarily object-oriented with some functional features. | Multi-paradigm: object-oriented and functional programming. |
| Typing | Dynamically typed. | Statically typed with type inference. |
| Performance | Interpreted, lightweight, and fast for scripting but not as fast as compiled languages. | Compiled (JVM, native, or JavaScript), generally faster and suitable for production applications. |
| Libraries and frameworks | Limited standard library, few third-party libraries or frameworks. | Rich ecosystem, access to Java libraries, and many frameworks (e.g., Ktor, Spring). |
| Community and support | Small, niche community with limited resources and support. | Large, active community with strong support from JetBrains and extensive resources. |
| Learning curve | Gentle learning curve due to simplicity and minimalism. | Moderate learning curve, especially for those familiar with Java or modern programming languages. |
