Functional programming is based on mathematical functions. The Higher order functions are possible, as Scala programming language acts towards the functions as first-class values, which implies that analogous to some other values, functions can even be passed as a parameter or can be returned as an output, which is helpful in supplying an adjustable method for writing codes. A function has a side effect if it does something other than simply return a result, for example: 2.1. In Functional Programming, the Hask category has a special role. The course is taught by Martin Odersky himself. The beast combines both the aspects of Functional Programming as well as of Object-Oriented Programming and outputs it as a high-level language..

Offered by École Polytechnique Fédérale de Lausanne. FILL IN GAPS. As per the official documentation, Functions are first class objects in Scala, which means that they can -. Functional Programming in Scala (2) — The Map function. There are also a number of convenient language features in Scala (such as type inference, implicit type conversions, and for comprehensions) that can make Scala code much more concise and expressive than Java.

Scala, like every programming language, provides us with the ability to write loops. Scala is a modern multi-paradigm programming language designed to express common programming patterns in a concise, elegant, and type-safe way. Scala lets you write code in an object-oriented programming (OOP) style, a functional programming (FP) style, and even in a hybrid style, using both approaches in combination. This trend is driven by the adoption of Scala as the main programming language for many applications.
