how to use for iv in pairs
Using "for k, v in pairs" in Lua
To use the "for k, v in pairs" loop in Lua, follow these steps:
- Initialize the Loop:
- Begin the loop with the "for" keyword followed by the loop variables, in this case, "k" and "v".
- Use the "in" keyword to specify the table to be iterated over.
- End the line with "do" to indicate the start of the loop body.

- Iterate Over the Table:
- Within the loop body, use the variables "k" and "v" to access the key-value pairs of the table.
- Perform any desired operations using the key-value pairs within the loop body.
[[SOURCE 9]]
- End the Loop:
- Close the loop body with the "end" keyword to indicate the end of the loop.

This loop is commonly used to iterate over all key-value pairs in a table in Lua.
