Lua has a simple syntax that is easy to both learn and read. The following is a simple script:
-- This is a sample Lua script
-- Single line comments begin with two dashes
--[[
This is a multi-line comment.
Everything between the double square brackets

]]
-- Lua is loosely typed
var = 1 -- This is a comment
var ="alpha" -- Another comment
var ="A1" -- You get the idea...
-- Lua makes extensive use of tables
-- Tables are a hybrid of arrays and associative arrays
val1 = 1
val2 = 2
my_table = {
key1 = val1,
key2 = val2,
"index 1",
"index 2"
}

freeswitch.consoleLog("INFO","This is a log line\n")
If script is executed from dialplan (eg: there is
an incoming call to manage) you have the 'session'
object which lets you manipulate the call:...
