In this tutorial, you will learn how to use lambda expressions and other functional literals provided by Kotlin for the Android platform.

Lambda expression is a simplified representation of a function. It can be passed as a parameter, stored in a variable or even returned as a value.

To practice using lambda expressions, you will build a simple app to save and manage your favorite songs. It will have the functionality to:

  • Add songs to a Favorite list.
  • Display favorite songs on a list with playlist range.

While doing so, you will explore the following Kotlin topics:

  • Lambdas
  • Anonymous functions
  • Higher-order functions
  • Closures

Time to start learning!
