User:OrenBochman/Lua Tables

The table is Lua's primary data structure

Creating a table

numbers = {
   one = 1,
   two = 2,
   three = 3
}

Accessing a table element

return numbers.one -- returns 1

return numbers['one'] -- also returns 1

Numbered tables

africanFlatbreads = {
    'Aish Mehahra',
    'Injera',
    'Lahoh',
    'Ngome'
}

return africanFlatbreads[2] -- returns 'Injera'

Visiting each table element

• pairs: key/value pairs in random order

for name, number in pairs(numbers) do
...
end

• ipairs: Numeric keys in ascending order

for index, bread in ipairs(africanFlatbreads) do
...
end
