Scala Infographic – A Complete Path to Learn Scala For Beginners

What is Scala?

Scala was designed by Martin Odersky and first publicly released in early 2004. It is a hybrid programming language and is general-purpose. This means it observes a combination of functional and object-oriented programming. Through this Scala infographic, we will provide you with all the basic information about the Scala programming language. It is a concise, high-level programming language that runs on JVM (Java Virtual Machine).

Scala: Functional Programming + Object Oriented Programming

Scala first showed up in 2004 on the Java platform. In March of 2006, version 2.0 came along. Ever wondered why we call it Scala? The name is a portmanteau of the words scalable and language. This highlights its capability to grow with its users’ demands. Since source code in Scala compiles to Java bytecode, it is language-interoperable with Java. This is because the bytecode lets executables run on the JVM (Java Virtual Machine). And like Java, Scala uses a curly-brace syntax; it also uses many of Java’s libraries.

Developers are often amused with Scala features like currying, immutability, type influence, lazy evaluation, and pattern matching.

Why is Scala a Great Programming Language?

Scala has many benefits to it:

  • More productive than any other language – When we compare Scala to Java and Python programming, we find Scala to be more productive and faster as a language. Scala allows developers to use features of both functional and object-oriented languages. Concise code is one of the features of Scala which make it more productive.
  • Avoids deadlocks – Scala provides several ways to avoid deadlocks.
  • No language baggage
  • Offers less boilerplate

Scala Versions

There have been 74 versions of Scala by now. Currently, we use Scala 2.14; Scala 3.0 will release around early 2020. It will ship with these features-

  • Scala 3.0 will promote programming idioms
  • It will simplify things wherever possible
  • It will consolidate language constructs; this will improve consistency, performance, ergonomics, and safety
  • Eradicate inconsistencies and anomalous behavior
  • Ensure the design fits well together
