JavaScript::Generator3pm

Boxed perl object of a javascript generator

Overview

Generators were introduced in JavaScript 1.7. When you 'yield' from JS you'll be returned an instance of this class that you can use to retrieve the next value from the generator.

For example

  function fib() {  
    var i = 0, j = 1;  
    while (true) {  
      yield i;  
      var t = i;  
      i = j;  
      j += t;  
    }  
  }  
  
  var g = fib();  
  for (var i = 0; i < 10; i++) {  
    document.write(g.next() + "<br>\n");  
  }
