Scala is a modern programming language that combines the features of both object-oriented and functional programming. It runs on the Java Virtual Machine (JVM), which allows it to interoperate seamlessly with Java code. This makes it a popular choice for developers who want to leverage existing Java libraries while enjoying more concise and expressive syntax. Designed to be scalable, Scala is suitable for small scripts as well as large systems. It supports advanced features like pattern matching, higher-order functions, and immutability, making it easier to write robust and maintainable code. Its versatility has led to its adoption in various fields, including web development and data processing.
