In Lua, "table" is a fundamental type that can be used either as an array (numerical index, fast) or as an associative array. The keys and values can be of any type, except nil. The following focuses on non-numerical indexes. A table literal is written as { value, key = value, [index] = value, ["non id string"] = value }. For example:
In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also supported.

A table is a sequence, optionally supplemented by named keys: digit["two"]="2". Several table functions like table.concat will only work with the numbered values and ignore named keys. The metatable offers a large, optional set of methods for altering table behavior. For example, you can define a table to be callable like a function.
# is the length operator for tables and strings. array [0] = "z"-- Zero is a legal index. print (# array)-- Still prints 4, as Lua arrays are 1-based. The length of a table t is defined to be any integer index n such that t[n] is not nil and t[n+1] is nil ; moreover, if t[1] is nil , n can be zero.

The most frequently used general-purpose implementation of an associative array is with a hash table: an array combined with a hash function that separates each key into a separate "bucket" of the array. The basic idea behind a hash table is that accessing an element of an array via its index is a simple, constant-time operation.
Miami being in the US is a big factor, as it is the top market for the Italian luxury automaker, with Florida the second-biggest market for Lamborghini in the country, following California.
