**Topos** comes with a lot of array methods to deal with musical patterns of increasing complexity. Some knowledge of patterns and how to use them will help you to break out of simple loops and repeating structures. The most basic JavaScript data structure is the [Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array). Topos is extending it with custom methods to describe patterns that evolve over time. These methods can often be chained to compose more complex expressions: <ic>[1, 2, 3].repeatOdd(5).palindrome().beat()</ic>.
