Summary
So, let's summarize what we have learned in this chapter. We started with the most basic val and var variable constructs. Then, we learned how we can write literals, and what data types we have in Scala. We then studied the interesting class hierarchy in Scala, in which we talked about unified class hierarchy and value and reference type classes. Later, we learned one of the most important concepts of Type Inference in Scala. After that, we started with operators, and their precedence. We learned how wrapper classes provide all the richness of functionalities to us as programmers. Finally, we learned a simple, but useful way of processing our String literals using interpolators. Now, it's clear that with some more practice of all these constructs that we've learned we'll be ready to go further and learn about some logical and looping constructs that shape up our programs.
In the next chapter, we'll discuss some looping constructs in Scala, logical constructs, and an introduction to...
