A powerful, efficient, lightweight, embeddable scripting language.
When to Use
- Game Development (Roblox, WoW, Love2D)
- Embedded Systems
- Configuration scripting (Neovim, Nginx)
- Extending applications
Quick Start
print("Hello, World!")
function factorial(n)
if n == 0 then
return 1
else
return n * factorial(n - 1)
end
end
Core Concepts
Tables
The only complex data structure in Lua. Used as arrays, dictionaries, sets, and objects.
t = { key = "value", [1] = "first" }
print(t.key)
Metatables
Allow changing the behavior of tables (e.g., operator overloading, inheritance).
Indices
Arrays are 1-indexed (start at 1, not 0).
Best Practices
Do:
- Use
localvariables by default (performance and scope) - Use standard libraries where possible
- Understand table length operator
#behavior with holes
Don't:
- Pollute the global namespace
- Ignore
nil(undefined variables arenil)
