Just a curious question. I'm trying to detect if a function is multiple currlies during the runtime; eg I want to make following statements both work

add(1, 2, 3); // 6
add(1)(2)(3); // 6
add(1, 2)(3); // 6
add(1)(2, 3); // 6

First I need solve is to detect if the function is processing a multi curlied arguments or not. Here is my testing cases.

isMultipleCurly()(); // true   
isMultipleCurly()()(); // true  
isMultipleCurly(); // false

so how can I check if function is processing multiple curlied arguments?

You could check if the returned value is a function – Dale Feb 02 '18 at 08:41
Do you mean "curried"? – Barmar Feb 02 '18 at 08:41
@Barmar, passing argument by curlies. (also my typo ...) – Weijing Lin Feb 02 '18 at 18:33
@Dale, the question is how can I check if there are curlies? – Weijing Lin Feb 02 '18 at 18:35
@WeijingLin What are curlies? The only thing I can think of like that is curly braces, which are `{}`, but you're not using that in your code. – Barmar Feb 02 '18 at 19:53
