What exactly is the "do" keyword for?
I've just been observing other people's code, and from time to time i see this "do" statement completely alone. Does this statement have any additional meaning to it? What exactly is it used for?
Example:
1 | do |
2 | print("Code") |
3 | end |

The "do" keyword can be used to create new scopes in code. Basically used for making a new environment for holding local variables, incase you don't want to make a new one.
Here's an example:
1 | do |
2 | local test = "hello" |
3 | print(test) -- hello |
4 | end |
5 |
6 | print(test) -- nil |

You could also explain do while to him. drahsid5 250 — 9y

Not needed. It's the do statement that creates a new scope for "while" and completes it. The "while" loop would be an entirely different topic. CodingEvolution 490 — 9y

Lua doesn't have `do while`, it has `repeat until`. This is also to *hide* variables so that you can keep things private in an implementation (modulescripts obviate this though) BlueTaslem 18071 — 9y

I think he was referring to the while loop, just ordered it wrong. CodingEvolution 490 — 9y
