Lesson 1 / 20
Setting up (what you'll need)
To run Scala you will need the following. Scala takes ideas from both object-oriented and functional programming, and because it runs on the Java virtual machine (JVM) it can be combined directly with existing Java code.
- A JDK (Java Development Kit): required, since Scala runs on the JVM.
- Scala itself: install it from the official site or through the
sbtbuild tool. - For an editor, the standard choice is VS Code with the
Metalsextension.
