In Functional Programming, we don't change objects in our functions, we pass them into other functions to be manipulated. Immutability helps preserve the ability to compose things. These examples contrast the advantages offered by Scala against an Object-Oriented language like Java,.
A Monad is an interface that simply specifies one form for data composition. A Monad should be ruled by certain laws. Scala is not as strict with these laws, and its focus is more practical than anything. From the language standpoint, the only traits that a Monad should have are the high-order functions flatMap and map.
These provide the tool to compose the data they contain, through the application of a function. The following example further explains this:. Imagine that every collection we know is a Monad in Scala terms. This would mean that we are able to compose the internal data in this collection simply by applying a function through map or flatMap.

There are many arguments and debate about Scala, but the major part of the arguments involves a variety of distinguished or factual shortcomings of Scala as a language.
This might feel unpleasant from the outside and arise the question why should I use Scala? What are the benefits of to use Scala? It was created with purpose o being better language specifically for aspects those are considered restrictive, very tedious and frustrating for developers.
The outcome is much cleaner and well-organized language which finally easy to use and productive. Scala's complex features promote better coding and offer a performance increase. Functions, macros, and tuples are just a few of the advancements Scala offers. Scala incorporates functional programming and object-oriented programming into a powerful language.
Scala enables you to explore functional and OOP features together that helps to develop imperative, logical, functional and OOP skills. You can use types associated with both data attributes and behavior attributes. Using first class Scala functions you can pass anonymous functions along with values.
That is an elegant feature of Scala and the most preferred features by developers to be popular. Scala is completely different language than Java, but developers does not have to reinvent the wheel. It allows compatibility and interoperability with Java. Scala uses the Java Virtual Machine to run. Developer can directly use code and libraries from Java into Scala class by importing Java package. Java developers can also call Scala code from their Java Code.
Scala provides a unique combination of language mechanisms that make it straightforward to add new language constructs in the form of libraries. In many cases, this can be done without using meta-programming facilities such as macros. For example:. In particular, the interaction with the mainstream object-oriented Java programming language is as seamless as possible.
Those Scala features without Java analogues, such as default and named parameters , compile as closely to Java as reasonably possible. Scala has the same compilation model separate compilation, dynamic class loading as Java and allows access to thousands of existing high-quality libraries. Tour of Scala. Welcome to the tour This tour contains bite-sized introductions to the most frequently used features of Scala. What is Scala? Scala is object-oriented Scala is a pure object-oriented language in the sense that every value is an object.
Scala is functional Scala is also a functional language in the sense that every function is a value. In particular, the type system supports: Generic classes Variance annotations Upper and lower type bounds Inner classes and abstract type members as object members Compound types Explicitly typed self references Implicit parameters and conversions Polymorphic methods Type inference means the user is not required to annotate code with redundant type information.
