This course is out of date

First there's no Timeline panel, now I find there's no Profiles panel. There's a panel now called Performance but this course doesn't cover this. When was this course made and published?

The issue is timeliness. To be fair to Nick, I'm sure at the time this course came out that the information was correct but a lot has changed then. It's all well and good to create new more up-to-date courses but people will still access the older courses because they don't know that they're out of date. That's why I think that this course ought to be scrapped. I also think that any tracks featuring out-of-date courses should be altered accordingly by substituting new courses for older ones. I've noticed that this course is part of the Front End Development track (third from the bottom).

I think organisational policy should require:

1) The scrapping of out-of-date courses 2) Their replacement with new, more up-to-date courses 3) The changing of the tracks to reflect this

The forum is a great place to get help from other students, but may not be the most expedient (or even certain) way to contact the staff.

You may want to also provide your feedback directly to the staff as described on the Support page.

I can say that I have observed courses being "refreshed" or completely replaced regularly, so it's probably just a scheduling/priority issue.

Yes, I agree. This course is WAY out of date. Almost all tabs in DevTools have changed drastically. Not useful.

I don't know how the update schedules are established, but the frequency of update requests might be a factor You may want to submit another request to the Support staff.

Click the "Customize and control DevTools" button on the upper right corner of DevTools. Then click on the "More tools" tab > "JavaScript Profiler". This is a start in the right direction. You can record your console activity here. I had to use the console tab on the bottom half of DevTools in order to run the "test()" function while recording. You'll see what I mean whenever you try it.

Also, open the "Memory tab" it has the "Heap snapshot" option.

This isn't an exact answer but with the "JavaScript Profiler" tool and the "Memory" tab you should be able to figure out the answers to the following quiz.

Good Luck!
