Python's iterable and iterator library for JavaScript.Parent isjs-library.

⚠️ Depending on your environment, the code may requireregeneratorRuntime to be defined, for instance by importingregenerator-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*.
