--
--  We can create/overwrite a file like this:
--
dataFile = io.open("media/configData.dat", "w+")  -- Open the file 'configData.dat' in 'overwrite' mode.
dataFile:write(json.encode(myData, {pretty = true}))  -- Write our data table to this file as JSON.
dataFile:close()  -- Close our file. We should always do this when finished.



--
--  To read our file back, we can do this:
--
dataFile = io.open("media/configData.dat", "r")  -- Open the file 'configData.dat' in 'read' mode.
print("Our file contains:", dataFile:read("*a"))  -- Print the contents of the file. Alternatively, we could use json.decode(dataFile:read("*a")) to get our original table back.
dataFile:close()  -- Close our file. We should always do this when finished.
