Thank you for sharing your knowledge.

I still haven't understood why this currying approach is considered. I think it's easier to destructure the parameters like this

const checkBankDetails({
  username,
  userNameRegex, 
  acctNumber,
  acctNumberRegex
}) => {}

It gives more flexibility on how the function should be called. But apart from that, thank you for writing this blog.

Thanks Osinachi. I appreciate your kind words. The purpose of the article was to create a confident Impression on seeing such a high-other-function or curried function. To your question, I would say, we don't need destructuring in this context. Especially when we do React by using the "connect". Eg: connect(mapToStateProps)(AnyComponent).

In this case, we have used a high-other function in such a way that closure is established between the "mapStateToProps" and "AnyComponent".

Please let me know if I answered your question.

Thanks again friend.

Oh yeah

Currying is useful when the inner function is defined by the user.
