[3] Lua is cross-platform software , since the interpreter of compiled bytecode is written in ANSI C , [ 4 ] and Lua has a relatively simple C application programming ...
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.
Lua patterns deliberately lack the most complex regular expression constructs (to avoid bloating the Lua code base), where many other computer languages or libraries use a more complete set. Lua patterns are not even a subset of regular expressions, as there are also discrepancies, like Lua using the escape character % instead of \, , and ...

It doesn't declare it, as you might be used to from other programming languages, and the function isn't executed until it is called. One can do more complex things than this, of course. For example: One can declare other local variables in addition to p , to hold tables of data (such as lists of Language or country names), that the module uses.
