Generator functions in JS

A generator function is a popular interview question for web development interviews in Javascript.

Basically, a generator is a function that produces a sequence of results instead of a single value, i.e you generate ​a series of values.

In the below video tutorial we can learn more about it in detail:

Code snippet for reference:-

function* getNames() {
yield "John";
yield "Jim"
const genName = getNames();console.log("genName",;console.log("genName 2nd Time",;function* autoIncrementer() {
let counter = 0;
while(true) {
yield counter++;
const counter = autoIncrementer();

Hope this helps in solving your concept about Generator functions in JS.
