What is Scala?

Scala stands for scalable language. It is a modern multi-paradigm programming language. It combines functional and object-oriented programming. Object-oriented makes it simple to design complex systems and adapt them to new demands and functional programming makes it simple to create things rapidly from simple parts and it is compatible with Java.
It adopts a big part of the syntax of Java and C. Except for the syntax, Scala takes other elements of Java-like as its basic types, class libraries, and its execution model. It is designed to convey general programming patterns in an elegant, brief & type-safe way.

What makes Scala scalable?

There are the two features of Scala i.e.

• Object-Oriented
• Functional

Because of these features, Scala is scalable.

The features of Scala are-

• Compatible
• Concise
• High-level
• Statically typed
• Object-oriented
• Functional
• Scala runs on the JVM
• Scala can execute Java Code.
