why does
function getSmallerValue(a, b)
if a < b then
return a
end
return b
end

work, like can someone explain why this works

What language is this? Please post a link to the exercise page where that code works.

``````function getSmallerValue(a, b)
if a < b then
return a
end
return b
end
``````

This is the Lua programming language.

How this works:
function getSmallerValue(a,b)

this is a function used to get the smaller value of numbers in a list of 2 numbers/digits

if a < b then
return a
end
return b
end

This section explains how the function will be worked. Imagine a and b as different numbers. if a and b is stated and a(as a number) has a lower absolute value than b, then the code will return a, because a is the smaller value out the two. Else, if not then the code will return b(since if a, the first number listed is not smaller than b)

Hope this helped
