One of the most exciting new features coming in JavaScript ES6 is a new breed of function, called a generator. Before generators, the whole script used to usually execute in a top to bottom order, without an easy way to stop code execution and resuming with the same stack LATER. Generators are functions which can be EXITED and later re-entered. Their context (variable BINDINGS) will be saved ACROSS re-entrances.

Generators allow us to stop code execution in between. So LETS have a look at a simple generator:

var generator_func = function* (){
yield 1;
yield 2;
};
var itr = generator_func();
console.log(itr.next());
console.log(itr.next());
console.log(itr.next());
