Hello in this free j s video, we are going to look at how to keep track of the performance of our application. AKA, we're going to track the frame rate. It couldn't be simpler to do this. If you just go to Mr. doobs GitHub page, Mr. Dube is the person who created free j s. If you don't already know the few ways you can get to you can even GitHub. Go to GitHub and search for Mr. Dubey. could Google GitHub Mr. Dubois could go to the free.js.
Website, add it there to Southern free Jester. org, go to GitHub, take you to the free jazz GitHub page. We're only interested in Mr. doobs GitHub page at the moment. And what we want from here is the stats dot j s. So if we just click on that, scroll down, this is what provides us so frame rate, milliseconds and the RAM usage, which is fantastic. There's a couple of different ways you can implement it. You can even include like download the JavaScript file and Included or more a, an easy way to do it is using the bookmarklet.
And all you do is copy this, go to your project and just have to start the script tag, paste this, what you want to do is actually get rid of JavaScript colon, because we obviously know that it's a JavaScript method. Get rid of that, save it. And now we're ready actually rate to refresh. There we go. We have a frame rate counter, which is displaying beef, I mean, 60 frames per second, got a nice little graph, we click on it changes to millisecond. So the time between frame click on it again, shows us RAM usage and it shows us a range as well for all the three different properties.
So it's that simple to get data for your game to see how well it is performing. Nothing more. To this video, that if you have any questions as usual, feel free to post them on our education platform, sonar learning dot code at UK forward slash questions dot php or feel free to contact us in any other way. There will be a link in the description to the source code from this video and the source code from every other video in the series. And as usual, thanks for watching and I hope you have a great day coding
