Lists can be modified in various after they are created. Starting from our original list:
local x = { "a", "b", "c" }
We can modify values in the list by assigning values to an index:
-- update a value in the table
x[2] = "x"
print(x[1]) -- a
print(x[2]) -- x
print(x[3]) -- c
We can insert values using the table.insert function:
-- add a value to the end of the table
table.insert(x, "d")
print(x[1]) -- a
print(x[2]) -- x
print(x[3]) -- c
print(x[4]) -- d
-- add a value to the end of the table
table.insert(x, 2, "y")
print(x[1]) -- a
print(x[2]) -- y
print(x[3]) -- x
print(x[4]) -- c
print(x[5]) -- d
Likewise, we can also remove items using the table.remove function:
-- remove a value from the table
table.remove(x, 2)
print(x[1]) -- a
print(x[2]) -- d
print(x[3]) -- nil
