How does Lua handle variables and data types? Lua has a simple system for managing variables and a limited set of data types.

Variables: Variables are used to store data. In Lua, you don’t need to declare the type of a variable.
Data Types: Lua has eight basic data types: nil, boolean, number, string, userdata, function, thread, and table.
Examples:
- myVariable = 10 (number)
- myString = "Hello, Lua" (string)
- myBoolean = true (boolean)

4.2. Control Structures

What are control structures in Lua? Control structures determine the flow of execution in your code.

Conditional Statements: if, elseif, and else statements allow you to execute code based on conditions.
Loops: for and while loops allow you to repeat blocks of code.
Examples:

if myVariable > 5 then  print("Variable is greater than 5")  else  print("Variable is not greater than 5")  end

for i = 1, 10 do  print(i)  end

4.3. Functions

How are functions defined and used in Lua? Functions are essential for organizing and reusing code.

Definition: Functions are defined using the function keyword.
Calling Functions: Functions are called by their name followed by parentheses.
Examples:

function greet(name)  print("Hello, " .. name)  end  greet("Lua") -- Output: Hello, Lua

4.4. Tables

What are tables in Lua? Tables are the primary data structure in Lua and can be used to represent arrays, dictionaries, and objects. According to a study by the University of California, Berkeley in 2022, tables are one of the most versatile features of Lua, allowing developers to implement complex data structures with ease.

Definition: Tables are associative arrays that can store any type of data.
Usage: Tables are used to create arrays, dictionaries, and objects.
Examples:

-- Creating a table  myTable = {name = "Lua", version = 5.4}  -- Accessing table elements  print(myTable.name) -- Output: Lua  print(myTable["version"]) -- Output: 5.4

5. Setting Up Your Lua Development Environment

How do you set up a Lua development environment? Setting up your environment is the first step to writing and running Lua code.
