What are Javascript Generators?

##what are generators##

  • They're pausable functions, pausable iterable functions, to be more precise
  • They're defined with the *
  • every time you yield a value, the function pauses until .next(modifiedYieldValue) is called
var myGen = function*() {
  var one = yield 1;
  var two = yield 2;
  var three = yield 3;
 console.log(one, two, three);
