What Is The Scope of Scala
Scala is a general purpose programming language, which provides the support for the functional programming and a strong static type system. It is designed to be concise, many of Scala’s design decisions aimed to address criticisms of Java.
Scala is a compiler based and a multi-paradigm programming language. It is fast, compact, and efficient. It combines object oriented and functional programming in one concise, high-level language.
Scala source code is intended to be compiled to Java bytecode, so that the executable code result runs on a Java virtual machine. Scala provides language interoperability with Java, so that the libraries written in either language may be referenced directly in Scala or Java code. Scala is object-oriented, which uses a curly-brace syntax reminiscent of the C programming language.
Scala also has many features of functional programming languages like Scheme, Standard ML and Haskell, currying, immutability, lazy evaluation, and pattern matching. It has an advanced type system supporting algebraic data types, covariance and contravariance, higher-order types and anonymous types.
Scala runs on the Java platform or Java virtual machine and it is compatible with existing Java programs. As Android applications are written in Java and translated from Java bytecode into Dalvik bytecode when packaged, Scala’s Java compatibility makes it well-suited to Android development.
Some programmers say that scala is faster than Java, it is 20 percent faster than Java. Both the Scala and Java programming languages run on JVM. Scala is a great language for an IDE that can warn you about errors immediately, even before you compile your code, and before you run it.
Scala runs on Java Virtual Machine and it depends on the person using Scala. This inter-operability feature of Java is one of the best options in Scala. This feature enables the Scala developer to use all the libraries of Java directly from Scala code.
Scala is also beneficial for Java developers as they can easily leverage their skills in Scala. There is also a possibility to call Scala code from Java and the user can easily write any part of a program in Scala and remaining in Java. This feature enables the user to write code in Java and Scala and work together with both these languages.
