In Piotr’s “Learn Kotlin Through Practice”, he teaches and builds examples from a great foundation. He’s especially good with his Kotlin function examples.
And, if you have an object oriented background in, say, Java, he does a great job in illustrating the differences.
When you get to his Unit Testing section, that’s where Piotr really shines. He gives full and complete examples, including functions and data classes.
“Learn Kotlin through practice” is a good way to learn and revise Kotlin. Not only would it be especially beneficial for newbies, but even an experienced developer might find it useful because of these features:
– it has lots of examples
