Scala as its name suggested Martin Odersky is a scalable programming language. The Scalability of Scala is due to the fact that it has the supports the features of both object-oriented programming and functional programming. Also, there are a lot of features like high-order functions, polymorphism, inheritance, tail-recursion, etc. All this makes it a scalable programming language.

Some features of Scala are:

  1. Scala is able to support the backend operations. As compared to Scala, the programs are a lot smaller and can do the task in a lot fewer lines of code.
  2. Scala's support for static Type: the code's state is defined at compile time improves runtime efficiency unlike in java. Scala allows the programmer to parameterize types with generics, and work on abstract and cross types that make its data handling efficient.
  3. Scala gives its users the power to create new frameworks and libraries to perform tasks more effectively. Like, it treats strings as sequences of characters and has a huge library backing its functionality.
  4. It is built over java and shares all the features with it as it works on JVM (Java Virtual machine) letting it use java code and inherit java classes and interfaces. This allows java users to move to Scala and work on their existing code and customize it.
