You call, I'll answer.

What's this all about?

The goal of the Call Kent Podcast is to get my answers to your questions. You record your brief question (120 seconds or less) right from your browser. Then I listen to it later and give my response, and through the magic of technology (ffmpeg), our question and answer are stitched together and published to the podcast feed.

I look forward to hearing from you!

My question is around the optimization techniques that a lot of people apply to React apps. I see very often how devs focus on executing their components only once or twice. What I think matters at the end is if there any changes in the actual DOM tree. If not they in theory should be ok to see your functional components fired many times.
