Scala Developer Salary Review and How to Save Your Budget?

Scala is a functional high-level language, combining features of object-oriented and functional programming. It runs on the same virtual machine as Java and is considered to be its main analog. The static types of this programming language help to avoid bugs in complex apps. With JVM and JavaScript runtimes, and access to huge libraries, you will get high-performance systems and stunning results.

Scala engineer salary is high enough, so programmers and their customers often compare it with Java to find out which programming language is more efficient or better suits to their projects.

Scala was created by Martin Odersky. It runs on Java Virtual Machine or JVM. It is the heart of the programming language, as it provides platform independence. Programmers also need JDK for the creation of Scala apps. It contains a huge variety of utilities and libraries for Java. It also provides the environment for the developer to write and run the code. In this environment, Scala cooperates with Java code stack and existing libraries. It is useful when you have to continue a project, which has been launched on Java. Scala programmer CV is often supplemented with Java knowledge.

Scala programming language has a set of features, making it differ from other languages:

  • Type inference. The coder doesn’t have to identify data type and function return type – the programmer is able to deduce the type of data. The last expression in the function identifies the return type of it.
  • Singleton objects. Static variables or methods are not usual for this language. Singleton objects are classes having only one object in the source file. These objects are used instead of class keywords.
  • Lazy computation. The performance is increased thanks to the lazy computation: the expressions are evaluated only when they are needed. Use the lazy keyword to declare a lazy variable.
  • Concurrency control. The actor model is located in the standard library of Scala. The coders use it to write concurrency code. There is one more platform and tool, designed for it: Akka. It is a separate open source framework providing actor-based concurrency. Coders distribute actors and combine them with software transactional memory.
  • Functions of the higher order. It takes a function as an argument or returns it as a function. In fact, it is a function able to work with another function. It helps the developer to create a function composition, lambda or anonymous functions and some other options.
  • Rich set of collection library. There you find mutable and immutable classes and traits to collect data – coders use them according to the requirements of the project.
  • Immutability concept. No one can modify the value of the declared variable. It helps to manage data and concurrency control. There are also mutable objects, which can be changed.

Scala vs Java

Scala is renowned for its mix of speed and expressiveness while using modern language features such as macros. Scala is younger than Java, but it already has many fans and followers.

Features of Scala Development

Other important features of Scala are:

  • Object-oriented – In Scala, just about every value behaves as a programming object.
  • Lambdas – Scala allows anonymous functions that can be invoked easily, adding to the programmer’s convenience.
  • Higher order functions – In Scala, functions can accept other functions as arguments, compose multiple functions together, and return functions as the result of a call.
  • Pattern matching – Scala uses powerful pattern matching capabilities such as those encountered in other functional programming languages.

main features of scala development

Differences with Java Language

Of the above features, the object-orientation trait is one that this language shares with Java, its older predecessor. Below, we show where the two programming languages differ most. Developers will need to be familiar with these important differences between the two.

As two JVM based languages, Scala and Java have many common features as well as noticeable differences. They produce the same byte code and run on one Virtual Machine. If you work with these two languages, it requires less integration. Moreover, the coders call Java from Scala and vice-versa and reuse components from the Java libraries in Scala. For writing of the Scala code, you can use most Java Integrated Development Environments: Netbeans, Eclipse, IntelliJ and other. One more common feature of these two languages: they both are object-oriented, but Scala also supports the functional programming paradigm.

Below we distinguish the points, where the two coding languages differ most of all:

  • Succinct and concise code. Scala is struggling for reducing of the number lines in the code. Such a result can be achieved by making clever use of type interference, treating everything as function passing or object.
  • Easiness in applying concurrency and parallelism. The coders are encouraged to write an immutable code, which makes common programming patterns elegant, concise and type-safe.
  • Simple learning curve. In comparison to Java, it is possible to learn Scala fast, as the learning curve is steep. However, when a little code is responsible for so many actions, it is difficult to predict the behavior of the code.
  • Built-in lazy evaluation. A keyword “lazy” added to the code helps to defer time-consuming computations to the moment they are absolutely necessary.
  • Nested Scala code. One can say, that Java is more readable because of this feature of Scala. It is quite difficult to see a function inside the function inside of an object inside of a class, especially if the code is poor-written.
  • Treating functions as variables. In Java, any function is an object, but in Scala, it is a variable – you can pass it around as an Object. It can give enormous power to the language.

How to Interview Scala Developers

If you want to hire Scala programmers, these are some common questions you can use to evaluate their knowledge:

  • What is a Scala map and how is it different from a set?  – This question tests the developer’s knowledge of basic data structures in Scala.
  • What are some advantages of the Scala programming language? – This question tests knowledge about important advantages of applying the programming language.
  • How is function currying used in Scala? – Here, you assess the developer’s ability to work with currying, a core functional programming feature of Scala.

Scala Developer Resume Example: How Does a Good Resume Look Like
