Ruby, with its rich set of array methods, provides developers with powerful tools to manipulate and analyze data structures efficiently. While some array methods are commonly used in everyday coding, there are others that, although lesser-known, can significantly enhance your coding capabilities. This article will explore five such methods, complete with practical code examples to illustrate their use.

Array#drop_while — Filtering Arrays Intelligently

The drop_while method is a sophisticated tool for filtering arrays. It drops elements up to, but not including, the first element for which the block returns nil or false. This method is particularly useful when you need to skip over a subset of elements based on a condition.

In this example, drop_while skips elements until it encounters the number 5, including it in the resulting array.
