Kotlin Vs Scala: Discover the Difference Between Them

Ever-changing coding needs have always occurred, causing programmers to reconsider using the proper programming language and resources to code. Java has been around for a long time, a very long time, since 24 years ago. It is simpler than that of other programming languages to use, write, build, debug, and learn.

However, its limitations such as slow performance, lack of support for low-level programming, poor features in GUI 4, and lack of control over garbage collection, are forcing Java developers to choose an alternative to Java, such as JetBrains’ programming language, Kotlin, which is now an officially supported language for Android development, or Scala, an all-purpose programming language that supports functional programming and a stride.

Why Kotlin is Becoming the Preferred Choice Over Scala for Android Development?

Today, we’ll look at how developers might decide whether to use Scala or Kotlin instead of Java. We will quickly discuss Scala vs Kotlin separately, as well as their applications, before continuing on to discuss the contrasts, advantages, and downsides of both, and eventually have you select which of these two meets your needs.

Before we begin, I’d want to ask the readers, “What are you searching for in the next programming language you’ll use?”

It is an evident question because the programming aims to drive the actual basis and requirement for building a language. Do you need a language that attempts to improve Java or one that allows you to do things that Java does not allow?

If the first argument applies, Scala may be the best choice; otherwise, it is a simpler language of programming like Kotlin.

Let us now briefly explore Scala and Kotlin separately.

Scala

Scala was created by Martin Odersky in 2003 and is a typical example of a broad sense, object-oriented computer language with a broad range of functional computer language capabilities and a powerful static type system. Scala, as the name implies, is very scalable, and this property distinguishes Scala from other programming languages.

When we say Java inspires Scala, we imply that programmers can code Scala similarly to how they code Java. Scala also allows for the use of several Java and library libraries within itself. It is intended to be able to describe typical programming patterns in an elegant, concise, and type-safe manner. Scala is a well-known programming language among developers and is rapidly ascending in the world of technology.

Although Scala has many advantages, it also has some disadvantages that make it ineffective. Scala’s advantages and disadvantages are listed here.

Strengths

Template Matching, Macros, and Higher-Kind Types are all fully supported
Has a highly adaptable code syntax
Increases Community Support
Allows for the overloading of operators

Weaknesses

Compilation is slow
A Difficult Binary Compilation
Incompetent in the Administration of Null Safety

Kotlin

Kotlin, created by JetBrains, was released as an open-source language in February 2012. To date, there have been several versions released, with the most recent being Kotlin 1.5.21, which was launched on July 27, 202. Kotlin is highly compatible with Java 6, the most recent version of Java on Android at the time of its release, and it has received widespread critical acclaim for this compatibility. Additionally, it offers several essential features that are available to Java 17 (released in September 2021) developers but not to Java 6 developers.

Kotlin’s compatibility with Java is seamless and faultless. This means that developers can simply call Java code from Kotlin and vice versa. The built-in null safety mechanism prevents the NullPointerException (NPE) from being displayed, making developing Android apps simple and enjoyable, which is something that every Android programmer desires.

The important points about Kotlin’s strengths and limitations are listed here.

Strengths

Uses a Functional Programming Methodology as well as an Object-Oriented Programming Style (OOP)
Has higher-order functions
Short, concise, and verbose expression
JetBrains and Google are also on board

Weaknesses

Pattern Matching is more limited
Size of Extra Runtime
Initial Code Readability
Official Support is in Short Supply
A more limited support community

Scala vs. Kotlin: Which is Easier to Use?

When it comes to choosing between Scala and Kotlin, ease of use is a critical factor for many developers. Both languages have their strengths and complexities, so let’s explore which one might be easier for you:

Kotlin- The Simplicity Advantage

Kotlin is renowned for its simplicity and ease of use. Its syntax is designed to be concise and readable, making it an excellent choice for developers coming from Java or similar languages. Here are some reasons why Kotlin is often considered easier to use:

Smooth Transition: If you have a background in Java, transitioning to Kotlin is relatively straightforward. Many Java concepts and idioms can be directly applied in Kotlin, which minimizes the learning curve.
Less Boilerplate: Kotlin reduces boilerplate code significantly compared to Java. Features like type inference, extension functions, and smart casts streamline development, making your code cleaner and more expressive.
Interoperability: Kotlin is fully interoperable with Java, allowing you to use existing Java libraries and frameworks seamlessly. This ensures a smooth integration process.
Android Integration: For Android app development, Kotlin is the preferred choice. It’s officially supported by Google and tightly integrated with Android Studio, making it easy for developers to create Android apps efficiently.

Kotlin is generally considered easier to use, especially for those with a Java background or those focusing on Android app development. Its simplicity and clean syntax make it a popular choice among developers. Now let’s talk about Scala.

Scala- The Freedom of Expression

Scala, on the other hand, offers a different kind of ease: the freedom of expression. While it may seem more complex at first, it becomes easier to use as you embrace its powerful features. Here’s why some developers find Scala appealing:

Functional Programming: Scala encourages functional programming, which can lead to more concise and expressive code. Developers who are familiar with functional programming paradigms may find Scala’s approach intuitive.
Advanced Features: Scala provides advanced features like pattern matching, currying, and higher-order functions, which can simplify complex tasks and improve code clarity once mastered.
Powerful Type System: Scala’s type system is robust and expressive, allowing you to create more precise and safer code. This can be particularly helpful for large and complex projects.

Scala, while initially more challenging, offers a unique experience for those who enjoy exploring new programming ideas and embracing functional programming concepts. It becomes easier to use as you become more comfortable with its advanced features.

The choice between Kotlin and Scala ultimately depends on your comfort level with each language’s approach and your specific project requirements. Consider your programming goals and preferences when making your decision.

Here are the main distinctions between Kotlin Vs Scala

Scala	Kotlin
Type inference	Efficient
Immutability	Functions for Extending
Singleton object	Huge Interoperability
Controlling concurrency	Reduces Runtime Crashes
Interpolation of strings	Smart Casting Mode
Higher-level function	Reliable and safe
Lazy computation of case classes and pattern matching	Adoption is inexpensive

Kotlin vs. Scala – A Syntax Comparison

Let’s have a closer look at the syntax of both Kotlin and Scala, highlighting their similarities and differences.

Variable Declaration

In both Kotlin and Scala, variable declaration is straightforward and follows a familiar pattern. Let’s consider an example of declaring a variable to store a name.

Kotlin

val name: String = “John”

Scala

val name: String = “John”

Here, we use the val keyword to declare an immutable variable (similar to final in Java) and specify the type explicitly.

Variable Mutability

Both Kotlin and Scala allow for variable mutability using the var keyword. This means you can change the value assigned to a variable after its initial declaration:

Kotlin

var age: Int = 25 age = 26

Scala

var age: Int = 25 age = 26

Function Declaration

Function declaration in Kotlin and Scala is also quite similar. Let’s define a simple greeting function as an example:

Kotlin

fun greet(name: String): String { return “Hello, $name!” }

Scala

def greet(name: String): String = { s”Hello, $name!” }

In both languages, we use the fun keyword in Kotlin and def keyword in Scala to define functions. The return type is specified after a colon.

Conditional Statements

Conditional statements, such as if and else constructs, are a fundamental part of any programming language. Both Kotlin and Scala provide similar syntax for these:

Kotlin

if (age >= 18) { println(“You are an adult.”) } else { println(“You are not yet an adult.”) }

Scala

if (age >= 18) { println(“You are an adult.”) } else { println(“You are not yet an adult.”) }

The if condition is followed by a code block enclosed in curly braces in both languages.

Making an appropriate language choice

Whether you have a preference for a particular programming language or not, making the right choice can significantly impact your professional success. Let’s delve into the key factors to consider when selecting between Kotlin Vs Scala.

1. Focus on the Outcome

The most crucial factor in choosing a programming language is the outcome you seek. Ask yourself: “What do I want to achieve with this language?” If your goal is Android app development, Kotlin is a clear winner. Android Studio, the go-to IDE for Android development, seamlessly integrates Kotlin, making it a top choice for Android programming.

2. Compatibility with IDEs

If you prefer working with Eclipse as your Integrated Development Environment (IDE), Scala IDE may be a better fit than the Kotlin Plugin. While it’s possible to use both languages in Eclipse, Scala IDE tends to offer a smoother experience. Some developers encounter challenges with the Kotlin plugin, especially in IDEs like NetBeans.

3. Simplicity vs. Freedom

Kotlin is an excellent choice if you value simplicity and quick compilation. It’s a more restrictive language but provides everything you need for efficient Android app development. Many Java developers find Kotlin to be a straightforward transition.

On the other hand, Scala is for programmers who thrive on exploring new ideas and enjoy the freedom of a feature-rich language. It’s a great choice for those who are passionate about functional programming, offering advanced features like currying and partial application.

4. Consider Your Task and Goals

Ultimately, the choice between Kotlin and Scala boils down to your specific task, working style, and goals. If you’re focused on Android development and want a streamlined experience, Kotlin is the way to go. However, if you’re eager to explore new programming paradigms and embrace functional programming, Scala might be your best bet.
