Frequently Asked Questions

How are TypeScript classes handled?

TypeScript classes are converted to Lua's metatable-based object-oriented programming pattern. Class inheritance is implemented using metatables, and methods are converted to Lua functions that maintain their behavior.

What happens to TypeScript interfaces?

TypeScript interfaces are used only for static type checking and don't generate runtime code. The converter removes interfaces while preserving the structure of objects that implement them.

How are array methods handled?

JavaScript array methods like map, filter, and reduce are converted to equivalent Lua table utility functions. These functions are automatically added to your converted code when needed.

When should I use the LuaJIT compatibility option?

Enable LuaJIT compatibility when targeting environments that use LuaJIT, such as some game engines and embedded scripting solutions. This ensures that the generated code takes advantage of LuaJIT's performance optimizations.

Limitations

While our TypeScript to Lua converter handles many common patterns, there are some limitations to be aware of:

  • Complex TypeScript features like generics, decorators, and namespaces may not convert perfectly
  • TypeScript-specific language features like enums require manual adjustment after conversion
  • Some JavaScript built-in objects and methods don't have direct Lua equivalents
  • The converter focuses on core language features rather than framework or library-specific code
  • Very complex class hierarchies with multiple inheritance patterns may need manual refinement

For best results, review and test the generated Lua code, especially for complex applications.
