Blocks and Iterators

  • Malay Mandal
Chapter

Abstract

Intuitively, a block of code is a set of statements that are grouped together. For instance, statements within a function (function body) or the block of code to be executed inside the while loop. However, Ruby has a special block feature that (while still being a group of one or more statements usually enclosed in flower brackets) has very interesting usages. It is especially useful in the context of iterator methods for collections.
