Thanks for the video. Any chance we can know how templating works ?

there is a mistake! Maps can have objects as keys! In Weakmaps the keys arent strongly held so there can happen GC. There is a great http203 episode about all the weak stuff.

strong guys don't study weak maps

But how are triggers triggered in vue reactivity?

[@DEVDerr]

They're triggered automatically by overriden default object getters and setters behavior, thanks to JavaScript Proxy API. Each time you call yourVariable.value, then instead of calling default getter => it calls trigger() on your object. That's why in new vue reactivity `.value` is so important. It's directly bound to JavaScript native Proxies
