TL;DR - You can access render time values in handlers without having to use anonymous arrow functions. Hint — leverage data attributes.

I don't think that I would like to place data that I already have in the DOM and then retrieving it again from the DOM, but there could definitely be some use cases for this approach. Thanks for sharing!
The example given isn't relevant. If the id is coming from the props object, one can simply read it from through the closure in which case passing the data as an id to the html element and reading it from the event is useless.
If performance is a concern, one can also create a new component, pass the the necessary data as a prop and define the callback in the child.
I guess the described method could be useful for optimisation when dealing with third-party components though.
The example was to give an idea that values can be stored as data attributes. I'll update the example to access state values so it's obvious.
I like it. Seems like a simple, down and dirty way to avoid using anonymous functions when there isn't a better answer. There are plenty of places where this would have been handy. Thanks!
it's just awesome
thx a lot, man
This is a really cool idea! I am currently using anonymous arrow functions in my components/apps, maybe I'll refactor and use this approach.
So simple - but perfectly effective. Nice!
