Global Variables

In Lua, a variable you create without the local keyword is a global variable by default. This means the variable can be accessed and used from anywhere in your script.

Here's how you create a global variable:

playerName = "Alex"
score = 100

Both playerName and score are global variables because they were declared without the local keyword. Once created, these variables can be accessed from any part of your program - inside functions, loops, or anywhere else in your script. Because any part of the program can change a global, most Lua code makes a variable local unless it really needs to be shared, as the next lessons show.
