In this video we will cover the basic syntax and capabilities of Higher-order Methods like Reduce, fold or scan in Scala. In Scala Reduce, fold or scan are most commonly used with collections in the form of reduceLeft, reduceRight, foldLeft, foldRight, scanLeft or scanRight. In general, all functions apply a binary operator to each element of a collection. The result of each step is passed on to the next step.
