My favourite talk was only 5 minutes long and came from Elie Rotenberg[0]. He demonstrated how React can be used to completely obfuscate the DOM tree. In practice it seems somewhat malicious to do this, however there may be some legitimate use cases too. [0] [this video]

Something like react-armor can make cryptographically unpredictable class name, tree structure and tag name obfuscation. But it won't be enough if the ad itself is not written with the same toolkit. [LINK] [this video]

Or they can already do dom obfuscation like react-armor, it can make cryptographically unpredictable class name, tree structure and tag name obfuscation. [LINK] [this video]

It reminds me of a lightning talk I gave at ReactConf some time ago :) Basically forward-shuffling the component tree to produce HTML that will be really hard to match using CSS Selectors usually found in adblockers and other DOM-targeting scripts. Code: [LINK] Video: [this video]
