Language comparison
Key differences between Carbon and JavaScript
| Characteristic | Carbon | JavaScript |
|---|---|---|
| Syntax | C-like, designed to be familiar to C++ developers, with modern enhancements. | C-like, but more flexible and dynamic; syntax is less strict and more permissive. |
| Paradigm | Primarily multi-paradigm with a focus on object-oriented and generic programming. | Multi-paradigm: supports object-oriented, functional, and imperative programming. |
| Typing | Statically typed with strong type checking. | Dynamically typed with weak type checking. |
| Performance | Designed for high performance, close to C++. | Interpreted or JIT-compiled, generally slower than compiled languages like Carbon. |
| Libraries and frameworks | Limited, as it is a new and experimental language. | Extensive, with a vast ecosystem for web, server, and desktop development. |
| Community and support | Small, early-stage community with limited resources. | Large, mature, and active global community with abundant resources. |
| Learning curve | Steep, especially for those unfamiliar with C++-like languages. | Gentle, widely considered beginner-friendly. |
Common questions
Frequently Asked Questions
How do I convert Carbon to JavaScript?

What are the main differences between Carbon and JavaScript?
Carbon and JavaScript differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Carbon construct to its closest JavaScript equivalent. See the comparison table below for the key differences between Carbon and JavaScript.
Is the converted JavaScript code accurate?
The AI produces high-quality JavaScript code that preserves the behavior of your original Carbon code and follows JavaScript conventions. It handles common patterns, data structures, and idioms for both Carbon and JavaScript. For large or performance-critical code, review and test the JavaScript output before using it in production.
Can I convert an entire Carbon project to JavaScript?
You can convert Carbon files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Carbon to JavaScript.
