Scala enough to give you a preliminary idea of Scala's power and capabilities and whet your appetite for learning the language. Scala also has many functional programming facilities, including features found in advanced functional languages such as Haskell, and tries to be agnostic between the two paradigms, leaving the developer to choose between the two paradigms or, more often, some combination of them. For Scala's contributions, discussions on the evolution of the language, the standard library, discussions on the evolution of the Scala platform and more. I'll walk you through this What is Scala article so you can understand Scala's true capabilities.
Scala is a type-safe JVM language that incorporates both object-oriented and functional programming in an extremely concise, logical and extraordinarily powerful language. Scala is a pure object-oriented programming language (in the sense that every value is an object) that provides the features of functional languages (in the sense that every function is a value) as well. The popularity and use of Scala is increasing rapidly, as evidenced by the growing number of vacancies for Scala developers. Yes, it may seem more complex to the Scala novice, but once you fully understand the concepts behind it, Scala code will seem much simpler than Java code.
These were the features of Scala and we will go into some of the frameworks Scala is capable of supporting. You will get a complete knowledge about the scala programming language, HDFS, Sqoop, Flume, Spark GraphX and messaging system like Kafka. They then switched their backend to Java and used Scala as their new programming language to handle big data using the Hadoop and Spark frameworks which worked spectacularly. One of the best similarities of Scala and Java is that you can code Scala the same way you code Java.
Some of the more complex features of the language (tuples, functions, macros, to name a few) ultimately make it easier for the developer to write better code and increase performance by programming in Scala. As a result, there are certainly code distinctions and paradigm shifts that can make early learning of Scala programming a bit more difficult, but the result is a much cleaner and well-organised language that is ultimately easier to use and increases productivity.
