Scala Functional Programming and Collections

Programmers with some experience of programming in another language looking to get a start in Scala

Prerequisite
None

Expected Duration
94 minutes

Description
Scala mixes programming paradigms, and so presents a challenge to programmers coming from any other language. This course explores the use of functional programming in Scala as well as the Collections library and its uses.
