Confused about the millions of career options available in the IT sector?

Fret not. We have got you covered.

After doing a comparative analysis, we realized that majority of students and early professionals are clueless about their career choices and decisions. They either choose something because of peer pressure or just because some acquaintance advised them to pick it.

Among the countless career opportunities that are available in the market, one lucrative and promising career choice is becoming a Scala Developer.

Salary of a Scala Developer

On an average, a Scala developer makes around $175,500 per annum. Now, that's a significantly large amount. Scala developers mainly work with frameworks like Spark and Big-Data related technologies.

Thus, if you choose to become a Scala developer, then a stable career growth and hefty pay package will be there for you!

Understanding Scala

Scala--Scalable Language, is a multi-paradigm modern programming language. It enables you to express complicated programming constructs easily with a simple and elegant syntax. Martin Odersky created Scala. The first version of the language was released in the year 2003.

Scala helps you to seamlessly integrate the objected-oriented programming with functional programming. Scala is a Java-based programming language. So, if you are familiar with Java (or any other object-oriented language), then learning Scala would not be difficult for you.

Some advantages of Scala are:

  • External Librarirs
  • Compile
  • Concise
  • Error-Free
  • Readabile
  • Concurrent

If you are planning to learn Scala, then you can expect a decent payout. But, finding the best resources to learn the programming language can be a challenge.

We have curated a list of best Scala courses that provide you a roadmap for building your career in the domain from scratch. You can take these courses online as per your convenience.
