It uses the conventional thread-based model for concurrency. Kotlin is an open-source, cross-platform, statically-typed programming language developed by JetBrains in 2011. Some of these are − All types are objects; Type inference; Nested Functions; Functions are objects; Domain specific language (DSL) support; Traits; Closures; Concurrency support inspired by Erlang; Scala Web Frameworks. Since Scala was built for the JVM platform, its source code is designed to be compiled into Java bytecode so that the code generated can run efficiently on the JVM. The reasons may be different for different data experts. It is a pure object-oriented programming language which also provides the support to the functional programming approach. With traits however, inheritance is different. Compiled languages are faster than interpreted. Scala supports lazy evaluation while Java doesn’t support lazy evaluation.

Some of these are − All types are objects; Type inference; Nested Functions; Functions are objects; Domain specific language (DSL) support; Traits; Closures; Concurrency support inspired by Erlang; Scala Web Frameworks. Since Scala was built for the JVM platform, its source code is designed to be compiled into Java bytecode so that the code generated can run efficiently on the JVM. The reasons may be different for different data experts. It is a pure object-oriented programming language which also provides the support to the functional programming approach. With traits however, inheritance is different. Compiled languages are faster than interpreted. Scala supports lazy evaluation while Java doesn’t support lazy evaluation.
