Learn Scala with online courses and programs
Scala is a versatile, statically typed programming language that runs on the Java Virtual Machine. Learn Scala to enable concise and expressive code for a wide range of applications. Explore online courses delivered through edX.
What is Scala?
Scala is a powerful, statically-typed programming language designed to bridge the gap between functional- and object-oriented programming. Scala stands for “scalable language,” emphasizing its ability to scale from small scripts to large-scale software projects.
One of Scala’s key features is its compatibility with the Java Virtual Machine (JVM), which allows developers to leverage existing Java libraries and tools while benefiting from Scala’s more expressive and concise syntax. This interoperability makes it a popular choice for enterprises and developers looking to modernize their Java-based applications.1
Scala combines functional programming concepts, such as immutability and higher-order functions, with traditional, object-oriented programming. This fusion enables developers to write clean, maintainable code that is both concise and expressive. Pattern matching, a powerful feature borrowed from functional programming languages, is also a prominent part of Scala, simplifying complex data manipulation.2
Scala has gained popularity in fields like data science, web development, and distributed systems due to its robust support for concurrency and parallelism through constructs like Akka actors and Futures.3 It also offers libraries like Play Framework and Spark for building web applications and big data processing, respectively.

Having knowledge of Scala can open up opportunities in web development and programming in a variety of industries. Roles can include:
Scala developer: Writes, maintains, and optimizes Scala code for various software projects. This role can involve web development, building back-end services, or working on data processing applications using Scala and associated frameworks.
Data engineer or big data developer: Develops and optimizes data pipelines, ETL (Extract, Transform, Load) processes, and data processing applications.
Software engineer: Creates highly functional and efficient code for a wide range of applications.
Site reliability engineer: Responsible for automating deployment processes, managing infrastructure, and ensuring the reliability and scalability of software systems, which can involve writing Scala scripts and using Scala-based tools.
Each of these positions may demand distinct educational and skill prerequisites. For instance, you could acquire pertinent skills through shorter learning formats like standalone courses or boot camps, yet certain employers might prioritize candidates with a science or engineering degree, contingent on the position. Prior to selecting a particular learning trajectory, investigate the professional roles you aspire to and align your educational needs with your career objectives.
