why is scala preferred to java?

Scala's advantages Scala has an exact syntax, which eliminates repetitive code. It is both an object-oriented language and a functional language. This combination makes Scala the right choice for web development. Companies that have started using Scala are also contributing to the recent growth of Scala as a mainstream language.

Scala enough to give you a preview of Scala's power and capabilities and whet your appetite to learn the language. With a growing Scala community on the forums, it's not hard to find an answer to any question about Scala, which adds to your learning experience. Scala offers clean code, advanced features, functional and object-oriented programming in an open source package that leverages the Java environment. Along with the superior functional programming idioms available to take advantage of multi-core CPU architectures, Scala has the right mix of the popular object-oriented paradigm.

To advance your programming skills, it is good to learn at least one language from different paradigms, such as imperative, logical, functional and OOP, and Scala gives you the opportunity to explore both functional and OOP together. One thing you may not know about Scala is that it was originally developed at the Swiss university EPFL in an attempt to apply recent innovations in programming language research to a language that could gain traction in the mainstream, such as Java. Scala also offers closures, a feature that dynamic languages such as Python and Ruby have adopted from the functional programming paradigm. As a result, there are indeed code distinctions and paradigm shifts that can make it a bit difficult to initially learn to program in Scala, but the result is a much cleaner and well-organised language that is ultimately easier to use and increases productivity.

This combination of features makes it possible to write programs in Scala that are quite concise and elegant. For a Java developer, learning a classical functional programming language like Haskell or OCaml is much more difficult than Scala. In my opinion, for Scala to grow as a real Java alternative, given that Java 8 also has functional programming support, it has to attract more and more Java developers. As in other functional programming languages, in Scala, functions are first-class citizens (meaning you can pass them as values), and Scala also supports anonymous functions and currying (partial application of multi-argument functions).

The popularity and use of Scala is growing rapidly, as evidenced by the increasing number of vacancies for Scala developers.
