10 Reasons To Acquire Scala Programming Language
One of the questions my reader oftentimes inquire me is, shall I larn Scala? Does Scala has ameliorate futurity than Java, or why Java developer should larn Scala together with therefore on. Well, at that spot tin ship away last many reasons for learning Scala e.g. you lot are forced to larn because it been used inwards the novel companionship you lot joined or your solution architect decided to job it, but that's a unlike story. Here, we'll verbalize most reasons which encourage Java developers to larn Scala. Scala has emerged equally i the most powerful Java alternative inwards recent times. It's been the JVM linguistic communication of choice, leaving Groovy together with Clojure way behind, together with preferred equally the linguistic communication people desire to write most code in.
Scala has several strong points, strongest beingness the multi-paradigm language. With the superiority of functional programming idioms to accept payoff of multi-core CPU architecture, Scala has the correct mix of pop object-oriented paradigm.
It non entirely solves many of Java issues e.g. less to no boilerplate but also provides several best practices together with patterns, correct from the language. Despite providing fluency together with flexibility of dynamic linguistic communication similar Python, it's all the same a strongly statically typed linguistic communication to foreclose you lot from doing bad things, which simply hap at runtime inwards instance of dynamic language.
I am sure Scala developers volition add together many to a greater extent than reasons into this list, but beingness from Java background together with ardent supporter of Java, I think Scala definitely got something to offering together with next reasons brand a lot of instance for Java developers to larn Scala.
1) Multi-Paradigm language
Scala is a fleck unlike than Java, equally it supports 2 programming paradigm: object-oriented programming (OOP) together with functional programming (FP). For advancing inwards programming science it's skillful to larn at to the lowest degree i linguistic communication from unlike image e.g. imperative, logical, functional together with OOP, together with Scala gives you lot a run a jeopardy to explore both functional together with oop together.
The Pragmatic Programmer majority also advised you lot to larn a novel programming linguistic communication every year. Scala allows you lot to define types associated amongst both information attributes (with classes behaving similar C++/Java classes) together with behaviour attributes (with traits corresponding to Java interfaces).
Just similar inwards other functional programming languages, Scala functions are fantabulous (which agency you lot tin ship away transcend them closed to equally values) together with Scala also supports anonymous functions together with currying (partial application of multi-argument functions).
This combination of features makes it possible to write Scala programs that are quite concise together with elegant. Being multi-paradigm is i of the strongest selling points of Scala, which Java 8 has also attempted yesteryear introducing lambda expressions (see Java SE 8 New Features) but it all the same a duo of steps behind. I think, Scala volition ever last to a greater extent than functional than Java but that's topic of some other debate.
2) Interoperability amongst Java
In my opinion, Scala's selection of beingness inter-operable amongst Java is the best affair hap to Scala. Scala runs on the Java Virtual Machine (JVM) together with tin ship away interoperate nicely amongst Java code. This agency Scala developer tin ship away job Java libraries direct from Scala code.
Given, many Java developers are turning into Scala, this is the perfect way of leveraging their years of experience inwards real-world programming. It is also possible to telephone telephone Scala code from Java together with you lot tin ship away easily write portion of your plan inwards Scala together with the residuum inwards Java.
In short, Interoperability amongst Java gives Scala a huge potential to pop off mainstream, company programming language, equally therefore much of the world's code is written inwards Java together with therefore many developers are working inwards Java closed to the world.
3) Best Practices together with Patterns built-in language
One affair you lot mightiness non know most Scala that it was originally developed at the Swiss academy EPFL inwards an attempt to apply recent innovations inwards programming languages inquiry to a linguistic communication that tin ship away gain mainstream traction, much similar Java.
Several of best practices together with patterns are built into linguistic communication itself e.g. val declares top-level immutability, which is much ameliorate than the overloaded finally inwards Java, or const/read-only inwards C# amongst the weird rules associated amongst it.
Scala also offers closures, a characteristic that dynamic languages similar Python together with Ruby conduct keep adopted from the functional programming paradigm.
4) Expressiveness of language
When you lot compare Scala amongst Java equally I did inwards my previous post service most the difference betwixt Scala together with Java, Scala sure enough scores large over Java. Scala is inherently really expressive. There’s also tons together with tons of actually beautiful together with useful code written inwards Scala. This is attracting to a greater extent than together with to a greater extent than Java developers to larn Scala, who similar such beautiful code.
To plough over you lot an idea, hither is the give-and-take count plan written inwards both Java together with Scala, you lot tin ship away run into the divergence inwards the expressiveness of linguistic communication yesteryear yourself. Scala has achieved inwards simply i trouble what Java has taken to a greater extent than than 10 lines to achieve.
Btw, things tin ship away last improved on Java side yesteryear using Java 8 features, which is non used inwards this instance but still, Scala scores large over Java when it comes to concise together with create clean code.
5) Marketable
Which programmer doesn't desire to last marketable? One argue for learning a novel technology scientific discipline or framework is ever a ameliorate chore together with career growth. Learning Scala volition sure enough brand you lot to a greater extent than marketable. Many companies are using or migrating to Scala these days, including Twitter, LinkedIn, Foursquare, together with Quora.
Given Scala's marketing equally Scalable language, days are non far when the large Investment banks together with Financial organizations volition start looking Scala for their depression latency solutions. Similar to the advice given in Effective Java, Twitter has already shared best practices to prepare programs inwards Scala equally Effective Scala.
The founders of Quora spent a duo of months edifice a Scala spider web framework inwards social club to job Scala. Martin Odersky, the human being behind Scala, is instantly behind the start-up Typesafe for supporting commercial Scala development. All things are going inwards correct administration for Scala to grow equally the firstly alternative to Java.
6) Statically typed language
In general, statically typed linguistic communication similar Java prevents programmers from doing bad things, piece amongst a dynamic linguistic communication similar Python, you lot entirely know most a bad affair when you lot run the program.
Scala is best of both worlds. It feels similar dynamic, but its strongly statically typed languages e.g. Haskell or Java. Scala compiler is actually smart together with uses type-inference upwards to sum extent.
Scala provides type inference for variables together with functions, much ameliorate than limited type inference inwards Java together with C#. See Beginning Scala Programming to larn to a greater extent than most Scala linguistic communication features.
8) Growing Framework e.g. Akka, Play, together with Spark
One affair which you lot mightiness know that Scala is growing together with it's growing really well. Lots of skillful libraries, frameworks are coming around. Companies, who has started using Scala are also contributing to the recent increment of Scala equally a mainstream language.
There are some squeamish Scala spider web frameworks out there, including Lift together with Play. Akka, some other Scala based concurrent framework has already established itself equally toolkit together with runtime for edifice highly concurrent, distributed, together with error tolerant event-driven applications on the JVM.
Scala is also been used inwards Big information infinite along amongst Apache Spark which has farther fuelled its adoption yesteryear many Java developers interested inwards Big Data Space.
7) Growing Community
Along amongst language, Scala community is also growing together with growing really fast. Lots of programmers, including Java developers, are joining Scala bandwagon. More together with to a greater extent than framework, libraries are getting built on Scala.
More together with to a greater extent than IDEs are started to back upwards Scala syntax, much ameliorate back upwards inwards Eclipse together with IntelliJ. Great construct tool back upwards inwards SBT, Maven, together with Ant. Well, Part of this is because of Scala's capability equally beingness a language, which tin ship away equally terse equally many dynamic languages similar python, at the same fourth dimension tin ship away offering features similar static typing, type-inference, a mix of functional programming together with object-oriented programming.
In Recent surveys, Scala is also touted equally number i alternative of Java. In my opinion, to grow Scala has the existent alternative of Java, given Java 8 also has functional programming support, it has to attract to a greater extent than together with to a greater extent than Java developers. Getting large organisation similar Twitter to adopt Scala, sure enough helps the community, equally they conduct keep to a greater extent than resources together with influence.
9) Concise Syntax
Java has long been criticised for his verbose together with boilerplate syntax. Though it makes Java to a greater extent than readable, much similar English, Scala has laid a novel benchmark inwards beingness concise together with readable at the same time. Scala compiler, known equally scalac (remember javac) does to a greater extent than than you lot expect, it tin ship away generate toString(), equals(), hasCode() together with other things for you. Consider 2 code snippets of same shape written inwards Java together with Scala together with brand your selection :
public shape Book {
mortal finally String name;
mortal finally double price;
populace Star(String name, double price) {
this.name = name;
this.price = price;
}
@Override
populace int hashCode() {
int hash = 7;
hash = 23 * hash + Objects.hashCode(this.name);
render hash;
}
@Override
populace boolean equals(Object obj) {
if (obj == null) {
render false;
}
if (getClass() != obj.getClass()) {
render false;
}
finally Test other = (Test) obj;
if (!Objects.equals(this.name, other.name)) {
render false;
}
if (Double.doubleToLongBits(this.price) != Double.doubleToLongBits(other.price)) {
render false;
}
render true;
}
@Override
populace String toString() {
render "Test{" + "name=" + mention + ", price=" + toll + '}';
}
}
You tin ship away write the same thing, using Scala's instance shape equally below :
case shape Book(name: String, price: double)
Btw, you lot tin ship away also job Lombok library, i of the essential libraries for Java developers, to take away the boilerplate code related to getter, setter, equals, hashCode, together with toString. It tin ship away automatically generate those for you.
10) Relative Easy to learn
For a Java developer learning a classical functional programming linguistic communication similar Haskell, or OCaml is rather hard than Scala, In other words, Scala is relatively slowly to larn because of its oop functionality.
While taking their fourth dimension to larn Functional Programming, Java developer tin ship away all the same last productive inwards Scala yesteryear leveraging their existing noesis of OOP. Like Java, Scala has create clean syntax, squeamish libraries, skillful online documentation, together with lots of people inwards the manufacture using it.
With growing community of Scala at forums, StackOverflow, it's non hard to notice an response to whatever Scala questions, which adds to your learning experience.
That's all most Why Java programmer should larn Scala or some practical Reasons for learning Scala programming language. I am sure you lot volition notice many to a greater extent than reasons, i time you lot start exploring it. Once you lot start learning Scala, I am sure you lot volition LOVE IT. It non entirely got the cleaner OO code but also Functional capabilities, it feels dynamic (Like Python) but also has a static type scheme that tin ship away foreclose you lot from doing bad things. If you lot determine to larn Scala inwards 2019, hither are some of the useful resources for farther learning
