To expand slightly, the Elm compiler will help you out here and show you what you need to fix.
Given this function body
randomReturner n =
if n < 0.5 then
123
else
"abc"
The compiler will give you the following info:
The 2nd branch of this `if` does not match all the previous branches:
22| if n < 0.5 then
23| 123
24| else
25| "abc"
^^^^^
The 2nd branch is a string of type:
String
But all the previous branches result in:
number
Hint: All branches in an `if` must produce the same type of values. This way, no
matter which branch we take, the result is always a consistent shape. Read
<https://elm-lang.org/0.19.1/custom-types> to learn how to “mix” types.
Hint: Try using String.toInt to convert it to an integer?
