Introduction

Iterator is one of the most common design modes in daily development. Let's explore the iterator continent in the javacript world, here we go!

Iterables

Iterable sources

  • Array

  • String

  • Map

  • Set

  • Dom Elements

  • Arguments

Get iterableFn(used to generate iterator)

IterableFn can be derived from iterable source by its property: Symbol.iterator, for examp
