 The script code above is written in the Lua language. There are a few things to note about the code:
 
 - Defold reserves a set of built in callback *functions* that are called during the lifetime of a script component. These are *not* methods but plain functions. The runtime passes a reference to the current script component instance through the parameter `self`. The `self` reference is used to store instance data.
-- Lua table literals are written surrounded with curly braces. Table entries can be key/value pairs (`{x = 10, y = 20}`), nested Lua tables (`{{a = 1}, {b = 2}}`) or other data types.
+- Lua table literals are written surrounded with curly braces. Table entries can be key/value pairs (`{x = 10, y = 20}`), nested Lua tables (`{ {a = 1}, {b = 2} a}`) or other data types.
 - The `self` reference can be used as a Lua table that you can store data in. Just use the dot notation as you would with any other table: `self.data = "value"`. The reference is valid throughout the lifetime of the script, in this case from game start until you quit it.
 
 If you didn't understand any of the above, don't worry about it. Just tag along, experiment and give it time---you will get it eventually.
