Could someone provide an example of strict mode's double render helping?

Hello,

I've been trying to find an example of strict mode's double render feature helping to catch a bug in development. Can anyone provide an example of faulty code that you wouldn't catch outside of strict mode, but because it renders twice, it's easy to spot?

I've currently got strict mode turned off because I find the double render annoying (it often doubles the fetches to my server). Thank you!

​

**Update:** I get it! Thanks for your help!

If anyone is interested, this video explaining how to cleanup my fetches, helped me to understand how strict mode is helpful: [https://www.youtube.com/watch?v=Wu0rVQuawLU](https://www.youtube.com/watch?v=Wu0rVQuawLU)

I now understand that my fetches should not have been running twice. Thank you for helping!
