Inserting and removing elements from tables in Lua

Use table.insert() and table.remove().

Each take in 3 arguments:

• The table to operate on
• The index (optional, will default to the end of the table)
• The value to insert or remove

Adding a value to the start of a table:

local cart = { "apple" }

-- After this cart is { "banana", "apple" }
table.insert(cart, 1, "banana")

"Popping" a value from a table:

local cart = { "banana", "apple" }

-- After this cart is { "banana" }, fruit is "apple"
local fruit = table.remove(cart)
