Learning F# Functional Data Structures and Algorithms

Summary

This chapter was a deep dive into the ubiquitous IEnumerable, the F# data structure of sequences. Now, you should have a thorough understanding of sequences, the underlying operations, and query expressions. A sequence is a list of potential values computed on demand. Sequences can be created using a range expression, a sequence expression, the seq keyword, library methods such as init and initInfinite from the Seq module, or simply by treating some IEnumerable as an F# sequence. The Seq module has a large number of sequence-related operations available. You can easily implement custom enumeration (paging) in sequences by applying predicate-based filters. Last, but not the least, you should optimize the evaluations in the sequence and ...
