One of the few languages that are designed to grow with the user, Scala has been making huge splashes in the world of programming. The term ‘Scala’ is a portmanteau for ‘scalable’ and ‘language’ and the language is known for its ability to combine object-oriented programming and functional programming. Here are a few tidbits about Scala and why it is currently one of the trending languages on the market. Let’s see how it ranks up to another popular programming language, Java. https://www.eduonix.com/blog/infographics/infographic-on-scala-programming-language/ https://www.eduonix.com/courses/Software-Development/Learn-Scala-Programming-Language-from-Scratch

1. Today’s software engineers need a toolkit that allows a
choice when writing code between object-oriented or
functional, immutable or mutable, high-level abstractions
or low-level speed. Scala is a language that has evolved
fromitscreationin2003andprovidesthischoice.hence,itisa
popular choice for constructing applications that are
revolutionisingtheIndustry.
Scala is a type-safe JVM language that incorporates both
object-oriented and functional programming into an
extremely concise, logical, and extraordinarily powerful

Prosofscala consofscala
Simple and straightforward syntax.
Scala typically requires two-thirds less codes than
Java. The syntax is also more flexible. For
example, you can leave out periods between
method calls so that the code is more human-
readable and easier to understand.
Inherently immutable objects.
Scala’s programming language reduces many
thread-safety concerns that spring up in
traditional Java applications.
Fast implementation speed.
It allows for quicker implementation and
enhanced performance.
Hard to learn.
Syntactically, Scala is significantly different from
traditional Java. Furthermore, it presents a
completely different programming
paradigm—requiring a higher level.
Low ease of adoption.
When coding with a team, it’s rare to find
everyone writing purely in Scala. You need a team
of eager adopters for Scala to be feasible.
Limited backward compatibility.
Each major new release of Scala is incompatible
with the previous version.
List<Integer> ints = new ArrayList<Integer>();
for (String s : list) {
ints.add(Integer.parseInt(s));
}
val ints = list.map(s => s.toInt)
Scalavs.Java
There are some tricks in Java to shorten the code a bit, but not in standard usage.
Now consider a case where we have a list of strings that are numbers, but we want to convert that
list to a list of integers:
