Scala is a type-safe JVM (Java Virtual Machine) language released by Martin Odersky in 2003, which combines the functional and object-oriented programming paradigms into a concise and logical high-level language. Scala is sometimes seen as an attempt to create a better version of Java, and rightly so. 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. Scala is a type-safe JVM language that incorporates both object-oriented and functional programming in an extremely concise, logical and extraordinarily powerful language.
While it supports all the object-oriented features available in Java (and in fact, augments them in a number of ways), Scala also provides a large number of capabilities normally found only in functional programming languages. Scala Native is a Scala compiler that targets the LLVM compiler infrastructure to create executable code that uses a lightweight managed runtime, which uses the Boehm rubbish collector. Unlike Java, Scala has many features of functional programming languages such as Scheme, Standard ML and Haskell, including currying, immutability, lazy evaluation and pattern matching. Also, if you are well familiar with Java, C, C and Python, Scala would be the perfect choice to improve your programming skills and get better career opportunities at the same time.
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. One of the best similarities of Scala and Java is that you can code Scala in the same way that you code Java. As a result, there are indeed 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. ZDNet cites Scala as one of the most popular programming languages that can get you a job interview.
Yes, it may seem more complex to the Scala novice, but once you get a good understanding of the concepts behind it, Scala code will seem much simpler than Java code. This Spark certification training course helps you master both the essential skills of the open source Apache Spark framework and the Scala programming language. In terms of programming paradigms, Scala inherits Java's object-oriented model and extends it in several ways. The popularity and use of Scala is growing rapidly, as evidenced by the increasing number of open positions for Scala developers.
Scala enough to give you a preview of Scala's power and capabilities and whet your appetite for learning the language. Before you start reading this post, if you really want to learn Scala from scratch you can check out my previous post as well, which is one of them in this Scala series.
