In Partial Application, we create a lambda that takes a parameter and returns a lambda that does something with it.
Example:
multiply_function = -> (number) do
-> (another_number) do
number * another_number
end
end
doubler = multiply_function.(2)
tripler = multiply_function.(3)
puts doubler.(4)
puts tripler.(4)
In the above example, the lambda will take number as a parameter, and return a lambda. When you call this lambda with another_number, it will return the product of the two.
