Scala

Scala is a compiler based and a multi-paradigm programming language which is compact, fast and efficient. The major advantage of Scala is the JVM (Java Virtual Machine). Scala code is first compiled by a Scala compiler and the byte code for the same is generated, which will be then transferred to the Java Virtual Machine to generate the output.

Thus, the Scala became the key to success for managing the huge amount of big-data.

Now that we know the importance of Scala, let us now understand why actually it is the most preferred language in the present trends.

Why we need Scala?

• Scala is capable to work with the data which is stored in a Distributed fashion. It accesses all the available resources and supports parallel data processing.
• Scala supports Immutable data and it has support to the higher order functions.
• Scala is an upgraded version of Java which was designed to eliminate unnecessary code. It supports multiple Libraries and APIs which will allow the programmer to achieve Less Down Time.
• Scala supports multiple type Constructs which enables the programmer to work with wrappers/container types with ease.

Now that we have understood the requirements for which we needed Scala. Let us move into the comparison between the other languages and find out why it gets an edge over the other similar programming languages.

 Features of Scala

• Object-oriented Programing Language:

Scala is both a functional Programming Language and an object-oriented programming Language. Every variable and value which is used in Scala is implicitly saved as an object by default.

• Extensible Programming Language:

Scala can support multiple language constructs without the need of any Domain Specific Language (DSL)Extensions, Libraries, and APIs.

• Statically Typed Programming Language:

Scala binds the Datatype to the variable in its entire scope.

• Functional Programming Language:

Scala provides a lightweight syntax for defining functions, it supports higher-order functions, it allows functions to be nested.

• Interoperability:

Scala compiles the code using scala compiler and converts code into Java Byte Code and Executes it on JVM.

These were the Features of Scala and let us get into few of the frameworks of Scala is capable to support.

Frameworks of Scala

Akka, Spark, Play, Neo4j, Scalding are some of the major frameworks that Scala can support.

• AKKA - is a toolkit on runtime for building highly concurrent, distributed, and fault-tolerant applications on the JVM. Akka is written in Scala, with language bindings provided for both Scala and Java. 
• Spark- Framework is designed to handle, and process big-data and it solely supports Scala.
• Play-framework is designed to create web applications and it uses Scala in the process in order to obtain the best in class performance.
• Scalding- is a domain-specific language (DSL)in the Scala programming language, which integrates Cascading. It is a functional programming paradigm used in Scala which is much closer than Java to the original model for MapReduce functions.
• Neo4j- is a java spring framework supported by Scala with domain-specific functionality, analytical capabilities, graph algorithms, and many more.
