Return statement in Lua Programming
There are certain cases where we want to return a value from a given function so that we can use it later. These return values make use of a return keyword which in turn allows a function to return values.
There is an implicit return at the end of any function, so you do not need to use one if your function ends naturally, without returning any value.
It should be noted that the return statement is optional; if not specified, the function returns nil.
Also, only one return statement is allowed in a function.
Syntax
return expression/value
Now let’s consider an example where we would like to return a value from a function and then use that value and print it.
Example
Consider the example shown below −
function bar() return 2 * 10 end x = bar() print(x)
Output
20
The above example is the most common use-case of return statements. Let’s consider one more example of return statement in Lua.
Example
Consider the example shown below −
local v = 16
function foo()
if v == 16 then
return
end
print("foo")
end
print("Completed")Output
Completed
