can we get some spinners in react code example

Example 1: How can you print in lua/roblox

-- You can print string
print("Hello, World!")
-- You can print math
print(5 + 5)
-- You can print variables
local i = 5
print(i + 2)
-- You can print number
print(5)

Example 2: what to do when you have a button in scene builder but it doesn't appear in yellow text in the controller?

Try to make sure that the fxml page is connected to the controller
Usually in the border pane line
