We got to know what closures are and then we had a solid discussion regarding higher-order functions in Scala. That was essential as we were already using higher-order functions and we saw multiple forms of them. Afterwards, we looked at currying and talked about partially applied functions. We know that partially applied functions are different from partial functions and currying. So now we have a solid understanding of functions in Scala because we have investigated them thoroughly.
