Newly created alias is not an alias

[Alain Farmer]

Explaining this has made me come-up with the solution:

function isAlias pathToAlias
   return the aliasReference of pathToAlias is not pathToAlias
end isAlias

on testAliases currentFolder
   --
   put currentFolder & "test/" into targetFolder
   put currentFolder & "test-alias" into aliasPath
   --
   if there is not a folder aliasPath then -- alias of a folder is a folder
      create alias aliasPath to folder targetFolder
      if the result is not empty then answer the result
   end if
   --
   answer isAlias(aliasPath) & cr & isAlias(targetFolder) -- answers: true & cr & false
   --
end testAliases

Thank you, Mark, but the aliasReference is NEVER empty. 

Therefore cannot use: if the aliasReference of it is empty
to test if something is an alias.:

on testAliases currentFolder

   --
   put currentFolder & "test/" into targetFolder
   put currentFolder & "test-alias" into aliasPath
   --

   if there is not a folder aliasPath then -- alias of a folder is a folder
      create alias aliasPath to folder targetFolder
      if the result is not empty then answer the result
   end if
   --
   answer aliasPath & cr & the aliasReference of aliasPath -- answers targetFolder
   answer targetFolder& cr & the aliasReference of targetFolder -- answers targetFolder -- instead of empty
   --
end testAliases

I've never heard of a "there is an alias" reference. Instead try

create alias "myAlias" to folder "existingFolder"
if the aliasReference of "myAlias" is empty then
  die "it's not a reference!"
end if
