Currying is a technique in which a function accepts N parameters and turns it into a sequence of functions, each of them take 1 parameter.
In mathematics and computer science, currying is the technique of translating the evaluation of a function that takes multiple arguments into evaluating a sequence of functions, each with a single argument. For example, a function that takes two arguments, one from X and one from Y, and produces outputs in Z, by currying is translated into a function that takes a single argument from X and produces as outputs functions from Y to Z. Currying is related to, but not the same as, partial application.
Example in Ruby:
power_numbers = -> (x,y) do
x**y
end
In the above example, lambda take two parameters , and return the product of the two.
power = power_numbers.curry.(2)
In the above code we are setting a base number to which we will do an exponential calculation
puts power.(4) #16
The above code to calculate the value 2**4 and return 16.
