Scala is a statically typed general-purpose programming language that can be both object-oriented and functional, making it a very flexible language. 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, allowing the developer to choose between the two paradigms or, more often, some combination of them. Originally designed in Switzerland, Scala was released to the public in 2004 to address Java's famous verbosity, its focus on object-oriented programming and other problems.
Unlike Java, Scala has many features of functional programming languages such as Scheme, Standard ML and Haskell, including curation, immutability, lazy evaluation and pattern matching. The popularity and use of Scala is growing rapidly, as evidenced by the increasing number of vacancies for Scala developers. Simply put, Scala is an object-oriented language with functional programming elements that give the language great scalability. In terms of programming paradigms, Scala inherits the object-oriented model from Java and extends it in several ways.
Yes, it may seem more complex to the Scala novice, but once you fully understand the concepts behind it, Scala code will seem much more simplistic than Java code. 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 problem is prominent with Scala, where different versions of Scala have to be taken into account, especially during Scala version upgrades. Mainly, Kontlin captured many Scala developers who wanted to have a lighter Java than a new functional programming language.
In contrast, dynamic typing requires more testing to ensure program correctness, and is therefore generally slower, to allow for greater flexibility and simplicity of programming. For Scala contributions, discussions on the evolution of the language, the standard library, discussions on the evolution of the Scala platform and more.
