Combinator Pattern



​Combinator Pattern
...Seriously?
Damned there are so many patterns with all the fancy names, even one can create a separate vocabulary list & then wonder how much their given explainations match to their actual English language meaning.
Anyhow what can be said by a single person like me, noone cares as all are getting money to use these fancy names.
BTW, I came across this term for the first time in the below YouTube tutorial, one can watch once -
If you watch it then you might have seen the similar concept while doing coding, if you have done some serious coding.
But lets see as how it can be done using functional way. Below example is taken from the above video itself.
