Literal strings and assignments

When a literal string is assigned to a variable, a copy is made of the string, and the variable is assigned the copy of the literal string. For example, the following code:

for (var i = 0; i < 3; i++) 

{

   var str = "dog";

   Clib.strcat(str, "house");

   Clib.puts(str);

}

results in the following output:

doghouse

doghouse

doghouse

A strict C interpretation of this code would not only overwrite memory, but would also generate the following output:

doghouse

doghousehouse

doghousehousehouse
