I'd suggest to look at:

• the ECMAScript Harmony Project's wiki page on Generators,
• the Mozilla Developer Doc on Iterators and Generators,
• the JavaScript Tips page of the jslibs project,
• the Google Traceur Compiler's page on JavaScript Language Features,
• SO questions for "javascript generator yield".

A simple example is given in the Mozilla Developer Doc introducing the new features of JavaScript 1.7:

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++) {
  console.log(g.next());
}

Others are available in the documents listed above.

Real-World

For real world examples, you can for instance see:

• Google's own Traceur-Compiler's tests for EndYieldGenerator, and SwitchGenerator,
• or even the whole test battery for the yield keyword in Google's traceur-compiler,
• or the AcidMonkey tests, for instance this Pi Generator.
