An Introduction to Javascript Generators

By Gorilla Sun

Generators are a bit of an obscure feature of Javascript, and their usefulness might not be immediately evident. This article aims at explaining how they work and what they can be used for! We’ll first have a look at the syntax and how generators are typically implemented, followed by some use cases where generators come in really handy! We'll also briefly dip our toes into the concept of iteration, iterators and iterables and lastly also have a look at the lazy evaluation programming paradigm and how generators are one way to implement it!
