25+ Best Scala Courses & Certifications Online in 2022

Would you like to master Scala programming? 

Well, there are multiple programming paradigms to consider, namely OOP, functional, and imperative, among others. 

In order to be a competent programmer, you need to learn at least one language from each of these paradigms. This way you’ll become an all-around programmer who can work in various development environments. 

By learning Scala, you can check two paradigms off your to-do list, as it is both an OOP and a functional programming language language that is loaded with all the features of a modern programming language. 

Moreover, Scala is a vital building block for many popular frameworks today, namely Spark and Akka, in addition to being one of the top programming languages for data science

However, if I’m being honest, Scala can have a steep learning curve if you don’t choose the best Scala tutorials to get you started. So to properly deconstruct Scala, it’s essential to take the right Scala courses.
