Scala
Scala is a high-level, statically typed programming language that combines object-oriented and functional programming paradigms. It is designed to be concisely elegant and type-safe. Big data refers to the large use of Scala in combination with Apache Spark, a powerful framework for big data processing. Many of Scala’s features, as well as functionality in programming, make it quite suitable for effective large dataset processing. Besides, Scala is interoperable with Java, which makes the use of available big data tools and libraries be much better in its big data applications.
Scala is based on some core ideas, including:
- Object-Oriented Programming: Scala is a pure object-oriented language: every value is an object.
- Functional Programming: Scala combines features of functional languages; it is regarded as a hybrid language. Functions are first-class citizens.
- Immutability: It emphasizes immutability in collections and values one works with, thus making the code safe and predictable.
- Concurrency: Scala has great support for concurrent and parallel processing.
- Strong Static Typing: Ensures type safety and reduces runtime errors.
- Interoperability: Completely compatible with Java, which allows the usage of Java libraries and frameworks.
- Pattern Matching: Makes data-structure processing easy; makes code brief and readable.
