Scala enough to give you a preliminary idea of Scala's power and capabilities and whet your appetite for learning the language. So, is it worth learning Scala? That question seems broad, but learning Scala depends on the applications you are going to handle. As the name suggests, Scala is meant to scale, which speaks to the other aspect of some programming skills that drives up salaries and demand if it is used to build a complex infrastructure that serves a huge audience, employers are likely to pay quite a lot to someone who is proficient in it. Scala is a perfect technology if you want to migrate to functional programming from object-oriented languages like Java, Ruby or Python.
Scala meets all the needs of the modern world, so the demand for this programming language is only going to increase. Specifically, Scala emphasises the scalability of applications and databases by leveraging both functional programming paradigms and object-oriented concepts, such as classes and methods, to manage complexity in large code bases. 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 unifies OOP and FP, which is unique - no other programming language has done this before.
In addition, the Scala programming language has a reputation for being one of the most difficult languages in existence. Scala was created in 2003 and is becoming one of the most in-demand programming languages as it becomes a more important part of today's technologies. The popularity and use of Scala is growing rapidly, as evidenced by the increasing number of open positions for Scala developers. According to the StackOverflow survey, Scala is among the top 5 most loved programming languages.
Scala is a type-safe JVM language that incorporates both object-oriented and functional programming in an extremely concise, logical and extraordinarily powerful language. However, it is worth noting that, as Scala is an intermediate language, OOP and FP can be a turn-off for purists, but if used with care, it can be a most delightful programming language. Scala is heavily influenced by Java and has many similarities, so there is not much you can do in Java that you can't do in Scala.
