Scala - Learn Scala from Scratch

A Comprehensive Guide to Scala Programming. Learn Scala in easy Steps

The biggest advantage of Scala is that If you have a good understanding of Scala, every other programming language will be easy for you, since Scala is one of the most difficult language to learn. Scala Programming is based on Java, If you know Java syntax, then it’s pretty easy to learn Scala. We assume that you know Java. This course expects you to have a basic understanding of Java or atleast some other programming language.

At the end of this course, you will have a good understanding of Java as well as Scala. Scala is a object oriented language. Conceptually, every value is an object and every operation is a method call. The language supports advanced component architectures through classes and traits. Even though its syntax is fairly conventional, Scala is also a full-blown functional language.

Scala runs on the JVM. Java and Scala classes can be freely mixed, no matter whether they reside in different projects or in the same. They can even mutually refer to each other, the Scala compiler contains a subset of a Java compiler to make sense of such recursive dependencies. Functions in Scala are objects. The function type is just a regular class. The algebraic data types found in languages such as Haskell, F# or ML are modelled in Scala as class hierarchies. Pattern matching is possible over arbitrary classes. Even though Scala feels like a scripting language, Its syntax is concise and has low ceremony; thus its types get out of the way because the compiler can infer them.
