"Exploring the Pros and Cons of Scala - Is it the Right Choice for Your Next Project?"

Scala Advantages & Disadvantages

No matter how advanced, feature-rich, or user-friendly a programming language seems, nothing in the world of application development is perfect for every use case. Similar is the case with Scala, a very popular programming language that has gained much traction and is focused on functional programming, scalability, and high performance. In this blog, we’ll discuss the advantages and disadvantages of Scala.

What is Scala?

Before reaching a decision, it’s important to know what Scala is and how it is used. In simple words, Scala is a JVM-based programming language that is famous for functional and object-oriented programming. Launched by Martin Odersky and released in 2003, this programming language is used by many tech giants such as LinkedIn, Netflix, and Google. It’s safe to say that Scala is very popular and is used in some of the most popular software applications in the world. Some amazing features of Scala include:

·???????Type inference

·???????Singleton object

·???????Immutability

·???????Lazy computing

·???????Case class and Pattern matching

·???????Higher order function

·???????Traits

·???????Rich Collection set

Can you still wonder if Scala has some drawbacks? Yes, just like every great thing around the world, Scala also brings with it some disadvantages, which we’re going to learn in this blog. But before that, let’s have a look at the different types of Scala:

Standard Scala – This is the most common type of Scala programming language, which is a statically typed language that runs on the Java Virtual Machine (JVM). With Standard Scala, developers get access to object-oriented and functional programming features.

Scalaz Library – This is another common type of Scala programming language that offers additional functional programming features to the developers, allowing them to integrate advanced features into the applications.

Play Framework – Finally, there is Play Framework, which is an easy-to-use programming language that is aimed to help makes it easy to build web applications with Java & Scala. But the problem here is that this type of Scala doesn’t offer as much flexibility as other frameworks.

Advantages of Scala

Higher Productivity – One of the most amazing advantages or reasons behind the growing popularity of Scala programming language is that its programs are from 1/2 to 1/10 the number of lines of code in comparison to a functionally equivalent Java program. It is very simple to understand, the less number of lines a programmer has to write, the higher will be productivity and the less will be time to complete an application.

Higher Quality – Another great advantage of using Scala programming language for application development is that it encourages a functional programming style. This means an application developed with Scala will have fewer bugs. And when the bugs are fewer, it results in higher productivity and a higher quality product. It’s safe to say that the applications created with Scala will be better than the other programming languages.

Better Developers – It’s not always when a programming language is created with the aim to make good developers. This is the beauty of Scala, which helps programmers to pick up programming practices such as functional programming, which can be applied to other languages, such as Java. So, when you become a good Scala developer, you will also become good at Java development too. Since this programming language provides a positive environment for developers to learn something new, they will be happier with it and can create amazing products.

Fast Improving Ecosystem – Twitter was one of the early adopters of Scala. After a few years, many other tech giants like Netflix and LinkedIn are also using this language for creating amazing applications, making this one of the fastest-growing languages.

Functional & Advanced Features – We already discussed that Scala has a learning curve and it makes things easier for developers to learn and create amazing applications. Since Java is also a part of Scala, it makes this programming language more functional, allowing developers to gain access to advanced features. Some of the advanced features available with Scala include string comparison advancements, mixins, etc. We can say that even developers with non-Java backgrounds will be also accustomed to the features that Scala has to offer.

Best Suited For Web Development – While Scala is known as a great language for application development, it’s not limited to this area of development as this programming language can be also used for web development. Many global enterprises are choosing Scala over other languages as this language offers concise notation and code complexity optimization. Professionals in the field claim that Scala is a much better alternative to Java, C++, Go, etc. when it comes to web development.

Scala is Fun – One of the most amazing and obvious reasons behind the growing popularity of Scala is that this is very easy to work with and a fun programming language. Remember that there’s no life without challenges and Scala puts professional developers face-to-face in an entertaining, yet teachable way.

Disadvantages of Scala

Complex Learning – By now, you’d already know that Scala is one of the most amazing and advanced programming languages. We’d like to add here something that it incorporates features that are not familiar to many professional developers. So, it might be time-consuming to work with this programming language and understand its concepts. Many developers claim that Scala is more complex than Java, but when they learn it, things turn out quite impressive and interesting.

Limited Developer Pool – Unlike other programming languages like WordPress, Java, etc. not many developers work with Scala, which means you will have difficulty in getting your doubts clear, in case you face some challenges. It makes things tough for IT service companies to staff up with experts in the field. At the same time, it can also take some time for Java developers to come up to speed on Scala. As a result, this decreases the overall pool of available developers in the field.

Low Compatibility – Since this is a relatively new and less-used programming language, it is oftentimes not compatible when working with other systems or libraries. This can also hamper the quality of the project as well as make it time-consuming to work with the Scala programming language. Another point I’d like to add here is that the development tools for Scala might be less advanced than Java. For example, if you’re using IDE plugins in Java, you might be disappointed as IDEs are not yet as sophisticated.

Is Scala The Right Choice?

With a lot of advantages and limitations, many people ask “Should I use Scala or not?” Well, to know the answer, it is important to first consider the size and complexity of your project. For small projects with a limited set of requirements, Scala might not be a good choice. Similarly, if you have a large and complex software application to develop, you should consider using Scala.

It is also a recommended programming language for developers working with large datasets, as this has been found quite impressive at handling data manipulation tasks.

Your experience level also matters when it comes to choosing between Scala or other programming languages.

For beginners, it might be very tough to work with Scala. It is suggested to start with a more accessible language, such as Python or Java. But if you are an experienced developer and would like to work with an amazing programming language, then Scala could be a great choice for you.
