Nightmare Looping - node.js

Question

Hello, I am writing an application where I need to be able to loop through an array of urls. I know there is an example of how to do this but my issue is a little different, I will explain with some code.
nightmare
.goto('some url')
.evaluate(() => {
//evaluate code
})
.then(dataArray => {
var innerRun = function* () {
var returnData = [];
for (var i = 0; i < dataArray.length; i++) {
var item = dataArray[i];
yield nightmare
.goto(item.url)
.evaluate(function () {
return false;
})
.screenshot(item.imgPath)
returnData.push(item);
}
return returnData;
}
vo(innerRun)(function (err, ads) {
if (err) {
console.log("Error running", err)
return;
}
});
});
I would like to be able to loop that code by using an array of urls. I had issues implementing this I believe because I am already doing it inside the then. It would stop running once it hit the yield nightmare inside the then
var mainLoop = function* () {
for (var j = 0; j < urlArray.length; j++) {
var url = urlArray[j];
yield nightmare.goto(url)//same code as in example above
}
}
vo(mainLoop)(function (err, d) {
if (err) {
console.log("Error running", err)
return;
}
});
The above code is what I attempted to do. If anyone has any ideas it would be a huge help thank you!

Maybe try this:
var urls = ['http://example.com', 'http://example2.com', 'http://example3.com'];
var results = [];
urls.forEach(function(url) {
nightmare.goto(url)
.wait('body')
.title()
.then(function(result) {
results.push(result);
});
});
console.dir(results)
