<h2>What is Scala?</h2>Scala is a general-purpose programming language that combines object-oriented programming (OOP) and functional programming (FP).It runs on the Java Virtual Machine (JVM), allowing Scala applications to use Java libraries and integrate with the Java ecosystem.Scala is commonly used for backend services, data processing, distributed systems, and applications that benefit from expressive abstractions and functional programming. <h2>2. Why Learn Scala?</h2><h3>​Object-Oriented Programming​​</h3>​Scala supports classes, objects, inheritance, and traits.<pre class="__se__code-scala"> class Developer(val name: String) { def introduce(): Unit = println(s"Hi, I'm $name") } val developer = new Developer("Deepak") developer.introduce() ​ </pre><h3 class="__se__code-scala">Functional Programming</h3>Scala supports functions as values, immutable data, and collection operations such as <code>map</code>, <code>filter</code>, and <code>reduce</code>.<pre class="__se__code-scala">val numbers = List(1, 2, 3, 4, 5) val doubled = numbers.map(_ * 2) println(doubled) ​​ </pre><h3 class="__se__code-scala">Java Ecosystem</h3>Scala runs on the JVM and can interoperate with Java libraries.This is particularly useful for developers who already work with Java, Spring Boot, or JVM-based applications. <h3>Modern Backend Development</h3>Scala is used in backend systems, data processing, and distributed computing.
