Scala: Java go upwards

If you want to run your project on Scala, then, be ready to hunt developers. Scala is a multi-paradigm programming language with strong support of functional and object-oriented paradigms, designed to be used on the JVM. It has many features similar to ML-languages, Lisp, Haskell on the one hand, and C and Java on the other. Created by Martin Odersky in 2003 and has been constantly improved since then. Every year development in the Scala programming language is becoming more popular.
Scala is widely used in creating of many commercially successful applications, including LinkedIn, Foursquare, and many others, especially startups. The most famous user of Scala is Twitter. Nowadays, Scala is not #1 in web development, but with the help of Java-Scala enthusiasts, coders all over the world realize the value of lang.

Scala - Scala development

The main advantages of the language are:

Access to a huge number of existing Java-libraries;
A large number of libraries written for Scala and Scala;
Relatively high speed (2-3 slower than C);
Large developed ecosystem;
Easy to create DSL (Domain Specific language);
Scala is used in a number of powerful Internet companies (Twitter, LinkedIn, Foursquare);
The most common functional programming language in the industry;
There are a number of developed web-frameworks for Scala: Play, Scalatra and a number of others;
There is an implementation of the system of actors according to the Erlang principle;
Good GUI support (Swing, JavaFX);
Good assembly system, SBT;
Eclipse support;

But there are also some difficulties, that coders should work with:

Relatively high threshold of entry;
Language congestion.

Features of Scala

Scala is a functional programming language. That is, it focuses on functions and their return values. These functions always output the same result if the input is the same. Their behavior can therefore be checked for correctness with unit tests before the developer assembles them into a larger application. In addition, functional programming avoids changing the value of existing variables. The Scala compiler practically implements this principle. The row sequence Scala acknowledges with an error message. Avoiding such a mutable state makes functional languages interesting for parallel and concurrent programming: if no thread changes state on its own, everything will end up matching up.

Scala, however, as a pragmatic language, allows exceptions: Only the values assigned with “val” are immutable, but if the programmer advances “var” instead, it may change the value. The programming language also occasionally allows the imperative programming style – after all, there are tasks that solves this best.

To bring order to data types and functions, Scala uses object orientation like Java. All the Java gaming engines are easily accessible for Scala coders. The standard library as well as tailor-made code define classes from which one instantiates concrete objects. Classes bundle the properties of the objects and also contain methods: those functions which specify what the programmer is allowed to do with an object.

A hierarchical system of parent and child classes governs inheritance: Subclasses inherit properties and methods from the parent. Scala also knows abstract classes that cannot be instantiated themselves. They serve only to inherit common properties and methods to their subclasses.

Scala uses multiple inheritance using so-called traits, which are recorded almost as much as abstract classes. They roughly correspond to the interfaces in Java. A Scala class can inherit only a single parent class, but several traits.

It is all looks very sophisticated and there is. But specialists from can deal with it. Сontact us and we will be eager to help!
