An Overview of the Scala Programming Language
Scala a statically typed general-purpose programming language which target JVM (Java virtual machine). Scala supports both object-oriented programming (OOP) and functional programming (FP) styles.
Scala provides language interoperability with Java. Libraries written in Java can be used in Scala programs. And vice versa.
Like its ancestors, including C, C++, and Java, Scala uses curly-braces for blocks. Since Scala 3, however, there is also an option to use the off-side rule (indenting) to structure blocks, and its use is officially recommended.
Scala Main Features
- Scala is a JVM language. Scala programs are compiled to Java bytecode.
- Scala programs can use Java libraries, and vice versa.
- Scala is a multi-paradigm language. In particular, Scala supports object-oriented and functional programming styles.
- Scala supports algebraic data types.
- Scala supports data immutability, lazy evaluations, and pattern matching.
- Scala supports operator overloading.
- Scala is a block scoped language, like Java and other C-style languages.
- Scala 3 now supports syntax known as the off-side rule which allows structuring blocks using indentations (rather than curly braces).
- In Scala, checked exceptions are not used unlike in Java.
