Coding Scala in OO / FP

[Raymond Tong]

Scala makes it easy to code in OO or FP.
FP becomes more popular given it is always concise, expressive and no concurrency concern.
However, I always do it in OO way from beginning.
Is there any good books or tips to help me to switch to FP style?
Reading the book - Functional Programming in Scala ?
Or I should learn a pure FP language?

Learning a pure FP language is certainly not necessary, however it can be very useful and fun. "Functional Programming in Scala" is a good book, and the free Coursera course on Functional Programming principles in Scala is a great start as well.
