I've read over several examples of code using JavaScript generators such as this one.  The simplest generator-using block I can come up with is something like:  function read(path) {     return function (done) {         fs.readFile(path, "f...
I've got this recursive generator    var obj = [1,2,3,[4,5,[6,7,8],9],10]  function *flat(x) {     if (Array.isArray(x))         for (let y of x)             yield *flat(y)     else         yield 'foo' + x;  }  console.log([...flat(obj)])...
When passing parameters to next() of ES6 generators, why is the first value ignored? More concretely, why does the output of this say x = 44 instead of x = 43:  function* foo() {     let i = 0;     var x = 1 + (yield "foo" + (++i));     conso...
Consider this python code  it = iter([1, 2, 3, 4, 5])  for x in it:     print x     if x == 3:         break  print '---'  for x in it:     print x   it prints 1 2 3 --- 4 5, because the iterator it remembers its state across the loops. When...
The following code... Assume that the yield is inside a generator function and that something and else are defined, etc.  const value = something || yield else();   ...produces the following in V8 (Chrome or Nodejs):                  const start = in...
I'm writing some node.js to interact with sensors over a serial port connection.  The code for reading the sensor is asynchronous, naturally.  In my control code, though, I need to read a sensor, do something based on the value, read again, do so...
I have written a simple generator:  function geni() {     for(var i = 0; i < 10; i++)     {         yield i;     } }   And I get the error as below:      SyntaxError: missing ; before statement   [Break On This Error]           yield i;   Browser:...
I have a piece of code:  function * input(){     let array = [];     while(true) {         array.push(yield array);     } }  var gen = input(); console.log(gen.next("A")) console.log(gen.next("B")) console.log(gen.next("C")) c...
Here is my simplified code:  <html> <body>     <button onclick="testRun()">Click me</button>     <script type="application/javascript" language='javascript1.7'>         function testRun() {...
I'm trying to understand how yield works with recursion. For example, we have the following function in CoffeeScript that computes the factorial of a positive integer and returns the current cumulative product:  prod = 1 f = (n) ->   if n >...
