Lua operators are expressions used to perform calculations or to pass arguments between different value types.

Conditional Operators

if Query if something does or does not meet a certain condition
else Do something else if the query condition was not met
elseif Used to add additional if queries, if the initial query condition was not met
end This is used to close various queries or functions; there must be the same amount of end as if unless elseif has been used

Example 1: if condition is true...

local a = true

if a then 
 print("a = true")
else
 print("a = false")
end
