Python's iterable and iterator library for JavaScript. Parent is js-library.
⚠️ Depending on your environment, the code may requireregeneratorRuntimeto be defined, for instance by importing regenerator-runtime/runtime.
import {cycle} from '@iterable-iterator/cycle';
import {chain} from '@iterable-iterator/chain';
cycle( chain( [ 0 , 1 , 2 ] , [ 3 , 4 , 5 ] ) ) ; // 0 1 2 3 4 5 0 1 ...The goal of this project is to make (the parts that interest me of)
the following python constructs/idioms/libraries available in JavaScript under the
iter,next,StopIteration,list,sorted,map,zip,filter,sum,any,all,min,max- itertools
- itertools recipes
- more-itertools
- cardinality
reduce
The corresponding software library used to be released as a monolith. It has since been split up into multiple packages.
The packages are released under multiple npm @scopes.
Extra features are marked with a *.
