Introduction to Lua

Lua is a lightweight, high-performance scripting language commonly used as an embedded language in applications. Its simplicity, speed, and small footprint make it ideal for use in gaming, IoT devices, and scripting within software.

What is Lua Best Used For?

• Embedding into software as a scripting language (e.g., in games or applications).
• Developing game mechanics, especially in engines like Unity or Roblox.
• Writing scripts for automation and small, portable applications.
• Building lightweight, cross-platform programs.

Example Lua Script

This example demonstrates variables, a loop, and output.

-- Declare variables
local greeting = "Hello, Lua Programmer!"
local count = 5

-- Display greeting
print(greeting)

-- Loop through numbers 1 to count
for i = 1, count do
    print("Iteration: " .. i)
end

-- Print completion message
print("Loop completed! Total iterations: " .. count)

Explanation:

1. Variables: greeting is a string, and count is a number defining the loop range. Both are declared as local variables for scope management.
2. Loop: The for loop iterates from 1 to count. String concatenation is performed with ...
3. Output: The script outputs the greeting, each iteration, and a completion message using the print function.

Sample Output:

Hello, Lua Programmer!
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5
Loop completed! Total iterations: 5
