No waste of time, just very informative. Love this. Thanks guys. Great summaries John.

Looking to solve a memory leak in javascript at the moment, this video is a good help, but the task itself is soul destroying.

The code example would have been nice ...

[DavidGilbertson]

...and this goes for Breakpoint 1-7 as well. Great stuff guys.

Loreena excellent as usual. Great talk.

Going through this video of memory profiling. Really Insightful.

They say at 11:30 that a full garbage collection is performed when you do a Heap Snapshot. But I have found that there are some objects that remain that get cleared if I go into Timeline and click the Trash can icon. So it doesn't do a _full_ GC. The Timeline button cleans more things.

I can tell because I tagged these objects with a custom class, so I can search for them by the class.
I'm running Chrome 55.0.2883.75

Google photos I can't seem to my account and which is the add email don't work me but I Found in my photo's on mobile devices.

i think i need to take dev tools course ! this was great

[AndrewLuhring]

ok so like... now that you see the memory leak... what do yo do about it?

[DimaDesu]

I'm sure I understand the concepts, but I doubt I will figure out the problem spot in my code. Profilers are complicated, I think.

[pilotos]

Right, right... Correct, correct...

[JoeCritchley]

Good, but could have done with showing the demo's source code so we would know how to solve the issue in the demo.

[shouraikamikawa]

do you see the "Show advanced heap snapshot properties" option in the setting of chrome devtools? also Dominators view has not appeared. in version 62.0.3171.0 (Official Build) canary (64-bit)

Is there a quick way to get all Breakpoint episodes, besides searching them the usual way?

[JaredM]

Should be noted that the String is actually a UCS-2 string, it has most of the common, but not all, of UTF-16's character set

[jayarjo]

Thanks, so it's basically your playlist? :) I wish guys at google had a better way of sorting their videos rather than dropping them all in one big pile...

[jayarjo]

Is there a way to know when young memory is all out?

[dogoku]

the more you use it, the less complicated it will seem. After a few times you'll spot issues pretty fast. The hard thing is trying to refactor your code

[tabun]

Now I have learned how to detect memory leak, what would be my approach to remove the same?
