Supercharge Scala Future | FP-Tower - Console Exercises - retry and onError

The video tutorial covers the concept of retrying operations in Scala using higher-order functions. It introduces the retry function to handle repeated attempts of an operation until success or exhaustion of attempts. The tutorial also explains the use of package objects in Scala and how they will be deprecated in Scala 3. The implementation of the retry function is demonstrated, followed by refactoring existing methods to use this function. Additionally, the on error function is introduced to handle error-specific cleanup operations. The video concludes with testing and further refactoring for cleaner code.
