re: Optional chaining with React VIEW POST

FULL DISCUSSION
 

Hey !

I don't really agree with the conclusion of your article.
Using this feature now is quite dangerous for you web performances. The way babel is transpiling the optional chaining is quite disgusting (ok, like every polyfill), but this one is not really necessary.

If you try to use it everywhere is your apps, you should notice that your bundle will swell quickly.

I wrote an article explaining why we should avoid this feature for now.

 

I would agree that performance wise it's not the best and the transpiled code looks ugly. But if this starts to cause performance issues, I would rather optimize the Babel transpiling than trying to fix it inside the application. Transpiling won't be eventually needed for most of browsers so this is a "temporary" issue.
