Basic

Table is a mix of list and hashmap.

lua

mylist = {'a', 'b', 'c'}
mylist_length = #mylist
is_empty = next(mylist) == nil

Function	Description
`insert`	Insert an element at the specified position (defaults to last).
`remove`	Remove an element at the specified position (defaults to last).
`concat`	Flattens the list into a string (like `join` in other languages).
`sort`	Sort a list with an optional function.
`move`	Move elements from a table to another.
`pack`	Return a copy of the given table as list (indexed with numbers).
`unpack`	Return elements of list as different variables.

Insert value into table:

lua

table.insert(mytable, "new element")

Use pairs() or ipairs() to loop it:

lua

for index, value in pairs(mylist) do
    print(index, value)
end

Join elements with a newline:

lua

table.concat(mytable, "\n")
