is scala better than java?

The study concluded that Scala was faster than Java and Go when average developers write their code without thinking too much about optimisation. According to other websites, Scala is faster than Java. Some programmers even claim that Scala is faster than Java. Both Scala and Java run on JVM.

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 fact, the difference between the use of Java collections and Scala, in terms of built-in functionality, is so stark that it is typically very rare to find "for loops in Scala code - they are simply a sub-optimal way of applying operations to collections in most cases. 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. 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 understand the concepts behind it, Scala code will seem much simpler than Java code. As in other functional programming languages, in Scala, functions are first-class citizens (meaning you can pass them around as values), and Scala also supports anonymous functions and currying (partial application of multi-argument functions). 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. For those who are hearing about Scala for the first time - or who have heard of it only in passing - let's start with a brief look at Scala's history.

The popularity and use of Scala is growing rapidly, as evidenced by the increasing number of open positions for Scala developers. 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. Companies that have started using Scala are also contributing to Scala's recent growth as a mainstream language.

Scala is a type-safe JVM language that incorporates both object-oriented and functional programming in an extremely concise, logical and extraordinarily powerful language. With a growing Scala community on the forums, it is not difficult to find an answer to any question about Scala, which adds to your learning experience. Scala is enough to give you a preview of Scala's power and capabilities and whet your appetite for learning the language.
