Introduction to Scala

In this section we quickly go through the basic features of Scala. If you have programmed before, whether in Python, C, or Java, then this should be enough to get you started and to let you write your first Scala scripts. (If you have never programmed before, then you need to study basic programming first and come back later.)

You can also find the contents of this section in my Short Introduction to Scala on the Scala documentation page. You can print this and keep it next to your computer as a reference.
