Namespace Iterables

A set of functions for working with async generators/iterators.

Functions marked (S) work with endless iterables. That is, they don't require that an iterable finishes.

Conversions

• toArray Copy contents of iterable to an array
• map Yields value from an input iterable transformed (with possible change of type) through a map function. (S)
• fromArray Yields values from an array over time.
• fromIterable Yields values from an input iterable over time.

Comparisons

• every Returns true if predicate is true for every item in iterable
• equals Returns true if values in two iterables are the same at the same location, judged by a provided equality function
• max Yields the currently highest max value from an iterable (S)
• min Yields the currently highest min value from an iterable (S)
• unique Return a set of unique items, compared by reference. (S)
• uniqueByValue Return a set of unique items, compared by value. (S)

Filtering/finding

• filter Yields value from iterator that match a predicate (opposite of dropWhile)
• dropWhile Yields values from iterator, except those that meet predicate. Opposite of filter
• find Returns first value from iterator that matches predicate (S)
• some Returns true if a value matching a predicate is found. (S)
• reduce Reduce an iterable down to one value using an 'accumulator' function

Reshaping

• map Yields value from an input iterable transformed (with possible change of type) through a map function. (S)
• chunks Yields a certain sized 'chunk' of values from iterable as an array (S)
• concat Yields all the results of each iterable in turn (S)
• flatten For an input iterator of arrays, returns a flattened set of values
• slice Take a slice of an iterable
• zip Combines items at same position from iterables

Values

• fill Yields a fixed value for every value from an iterable
• combineLatestToArray Yield an array of values whenever a source iterable changes
• reduce Reduce an interable

Iterating

• forEach Runs a function for each value of iterable (S)

• until Calls a function for each value of an iterable. Value itself is ignored (unlike a forEach) (S)

Example: Importing

// If library is stored two directories up under `ixfx/`
import { map } from '../../ixfx/dist/iterables.js';
// Import from web
import { map } from 'https://unpkg.com/ixfx/dist/iterables.js'
