On paper, Scala runs on the JVM platform and should therefore work seamlessly with all JVM libraries and frameworks. In practice, try mixing Java and Scala code in the same project and you will quickly discover that this is not the case. Compiling to the same bytecode is not enough. 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.
Came to learn the following, I looked for something new, chose Scala because it was compatible with Java and could be a transition from OOP to functional programming. As a result, you can make a call from a Scala program to any of the standard Java libraries, or for that matter, to any custom library that is on the Java virtual machine classpath. Scala enough to give you a preliminary idea of Scala's power and capabilities and whet your appetite for learning the language. 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.
Although the parallels between Java and Scala are obvious, Scala differs in many ways, with its code being much more concise, cleaner and with its own advantages that are discussed throughout this post. Scala offers clean code, advanced features, functional and object-oriented programming in an open source package that leverages the Java environment. As Scala and the JVM continue to evolve, it is possible that some version of Scala will drop support for JDK 8, to take better advantage of the JVM's new features. He has been coding in Scala for the past six years, both in enterprise and open source projects, and is now dedicated to advancing the Scala platform itself.
Scala also has many facilities for functional programming, 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. 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. 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. After graduating, Adriaan joined the Scala team as a postdoc, working on the theoretical foundations of Scala as well as its implementation (dependent method types and implicit search, type constructor inference, the new 2.10 pattern matcher).
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. But why is Scala becoming so popular, especially in the cloud computing arena? Well, it actually has to do with the fact that the functional aspect of Scala makes it perfect for creating domain-specific languages (DSLs).
