The or statement can also be used to choose an existent value of a nil value. Here is an example: | |||
<pre> | |||
local y = x or 1 | |||
print(y) | |||
> 1 | |||
</pre> | |||
This printed '1' because variable 'x' doesn't exist and is therefore nil. So the or operator allowed us to choose 1 over nil. |

The or statement comes in handy when you want to check if one of the listed values is a certain value.
soul = true food = false try = false if soul == true or food == true or try == true then -- If any of the three comparisons are met, then continue with the code block print 'soul is always true' end Output: > soul is always true
The or statement can also be used to choose an existent value of a nil value. Here is an example:
local y = x or 1 print(y) > 1
This printed '1' because variable 'x' doesn't exist and is therefore nil. So the or operator allowed us to choose 1 over nil.
