Nice example.
I was getting below error.
ƒ is not defined at (index):35
Is ƒ a inbuilt function which I am missing. Can anyone give insight on why I got the error.
Anyway I fixed it by understanding what it has to do and created my own function with name ƒ.
If anyone else facing same problem.. try adding below code @ line 32 to resolve the issue..
ƒ = ((c) => ((d) => d[c]))
