Hire Scala Developers

Scala is a modern, general-purpose language that seamlessly combines functional and object-oriented programming. If you hire Scala developers they will use this powerful language that supports many functions similar to other highly popular languages ​​such as Python.

Scala uses common programming standards for coding and features exceptional productivity and efficiency. It also has features such as annotations, polymorphism, generic classes and upper and lower limits, among others.

Scala is statically typed and imposes a defined syntax for writing code. Classifies anything written outside the syntax rules as invalid and generates compilation errors. Scala is extensible and you can add new language constructs to it. This makes it easier to create libraries and incorporate additional features into the language. You can use features like string interpolation or implicit classes to do this.

Hiring Guide

Scala is a functional language, that is, it treats its functions as values ​​and can pass them as parameters to other functions. This is called higher-order function nesting. Furthermore, it is a lightweight language that can also define anonymous functions.

Scala is object-oriented and considers each value in the language as an object. Classes create objects and define behaviors for them. Another important component of Scala is Traits, a reusable cluster of abstract and non-abstract mechanisms used to implement methods and fields across classes.

Scala in today's industry

Martin Odersky created Scala. It was publicly released in 2004 and has been gaining popularity ever since. Over the years, many developers began to think of it as an alternative to Java.

It has been widely used to create highly scalable applications. Many companies such as Google, LinkedIn, Apple, SoundCloud, and Amazon have adopted Scala for their technology stacks.

Scala runs on the Java Virtual Machine (JVM). Java and Scala share similar environments and are interoperable. In fact, Scala can utilize Java classes and libraries, including JMSL. As a result, you can easily switch from one to another without any problems.

Problems finding the best Scala developer

Scala is a complicated language. To write industrial-grade Scala applications, you need to fully understand the language itself. Scala is great for increasing application productivity and scalability, but it can sometimes be difficult to work with. This is especially true if you are a beginner developer and haven't used it for a long time.

It also has some complex features like tuples and macros. Only an expert engineer can correctly handle these attributes without messing up the existing code base.

Scala engineers also need to regularly update themselves with the newest features, frameworks, and related technologies. They need to continually research new trends and generate ideas on how to optimize their products. This can sometimes be a challenge. This is one of the main reasons why Scala engineers are so sought after.

How to choose the best Scala developer

Scala developers need to have an impressive portfolio of skills that emphasize their experience in creating high-performance frameworks. Experienced Scala developers should be able to write code while working on other parts of the SDLC.

Scala developers must have experience in Java and be able to achieve interoperability between the two languages. They should also know about object-oriented programming.

Scala engineers must be able to perform software analysis and work closely with the QA team for debugging/error handling. They must also be able to recognize and research software trends relevant to their industry and apply them to improve their company's technology stack.

Scala Interview Questions

What is pattern matching in Scala?

Pattern matching is a powerful feature of Scala that engineers use to process messages. This checks the provided values ​​against a pattern. If the answer is yes, the value is sent to the internal component of the pattern linked to that value. It is very similar to Switch in Java. The keyword used for pattern matching is match.

These patterns can be made of constants, constructors or variables. Some common pattern types include XML patterns, tuple patterns, variable patterns, and extraction patterns.

Would you advise a client to choose Scala over Java?

Yes, because unlike Java, Scala is a precise language. Therefore, there is very little need for boilerplate code. This saves a lot of development time.

Scala also uses lazy evaluation to save compilation time by delaying time-consuming calculations. It also supports features like operator overloading, scalability, and expressive typing, whereas Java does not. As a result, an engineer can use Scala to code a diverse group of applications, such as real-time data streaming, batch data processing, and data analysis, among others.

Define options in Scala and explain their use

An option in Scala is defined as a container of a single element/null object. This means that if necessary, an object of an option is returned by a method instead of a null object/single object.

Options are commonly used in Scala programs to increase productivity. They make your code more readable and deal with null return issues.

What are some Scala frameworks?

Scala is a highly useful functional language for developing scalable applications. Some of the popular Scala frameworks include Anka, Spray, Slick, Finch, and Akka HTTP.

What is function curry?

Currying means converting a function that takes multiple arguments into a function that takes a single one. This makes the code easier to refactor when you need to call the same functions for different input parameters.
