This course teaches you programming in Scala, one of the most popular languages today, used by companies like Twitter and LinkedIn. Scala is a statically typed, high-level language that blends functional and object-oriented programming, making it ideal for building scalable applications.

 This course covers everything from basic concepts like Scala variables, type casting in Scala, and print in Scala to advanced topics like recursive functions in Scala, tail recursion, Scala classes, and more. Whether building scalable apps or improving your skills, this course will help you master Scala programming.
