The Lua C API is stack based. Lua provides functions to push and pop most simple C data types (integers, floats, etc.) to and from the stack, and functions to manipulate tables through the stack. The Lua stack is somewhat different from a traditional stack; the stack can be indexed directly, for example.
This help-page, Help:Lua debugging, explains issues of writing Lua script and debugging the source code, to remove errors or improve performance. Because Lua is a "semi-compiled" interpreted language, it does not prescreen for all common syntax errors, nor detect misspelled variables, which are only found at runtime when seeing the " Script ...
This text calls the Lua script itself, which is housed in the Module: namespace. The effect of this call is to send the information within the #invoke block to the Lua module, and to replace everything within the brackets with a piece of text that it sends back in return.
Here are some short points about Lua, for those who already know other computer programming languages and how to program. They focus mainly upon what you might find different in Lua. Lua is dynamically typed. There's no static typing at all.
This essay explains various issues about the execution speed and performance of Lua script in Wikipedia. The speed of using Lua modules can vary greatly, compared to similar markup-based templates, often ranging from 4x-8x times faster, or 180,000x faster when scanning text strings, which can exceed the 500-character parser-function markup limit as 64,000 characters or more.
LuaJIT uses two types of internal representation. A stack-based bytecode is used for the interpreter, and a static single-assignment form is used for the just-in-time compiler. The interpreter bytecode is frequently patched by the JIT compiler, often to begin executing a compiled trace or to mark a segment of bytecode for causing too many trace ...
