# seqnext - Sequences

A library of for "Sequences" in TypeScript / JavaScript.  

Written in TypeScript so you know the type definitions will always be valid and applicable.

## Sequences

The foundation of a Sequence in code:
```typescript
interface SeqNext<T> {
  (): [T, SeqNext<T>] | undefined;
}
```

You call a function, you get a value and another function poised to offer the next value.  
Or you get null, telling you there are no more values to be had.

This abstraction allows for a lazy model which is very useful when dealing with large amounts of data where you don't want all the values.
Or reading lines from a file.  Or rows from a database.  Or even reading an array.

Why would you want to use a Sequence for an Array?  The level of abstraction means you can test an array now, a database read later.  Also, there are a number of helpful tools for this Sequence.

This is inspired by Haskell's lazy paradigm and more concretely by [Microsoft F# Sequences](https://docs.microsoft.com/en-us/dotnet/articles/fsharp/language-reference/sequences).
