map Create populated in Lua

In Lua, you can create a hash, or table, using curly braces {} and assigning key-value pairs to it. Here's an example:

-- create an empty hash
local myHash = {}
-- add key-value pairs to the hash

myHash["name"] = "John"

myHash["age"] = 30

myHash["gender"] = "male"
-- print the hash

for key, value in pairs(myHash) do

  print(key .. ": " .. value)

end

-- Output: 

-- name: John

-- age: 30

-- gender: male

You can also create a hash with initial values using the following syntax:

local myHash = {
  name = "Jane",
  age = 25,
  gender = "female"
}
-- print the hash

for key, value in pairs(myHash) do

  print(key .. ": " .. value)

end

-- Output: 

-- name: Jane

-- age: 25

-- gender: female

In Lua, you can use table data types to easily create associative arrays, key-value pairs, and other data structures.
