On mount console.log is executed two times in @codesandbox/sandpack-react

[VladSez]

On initial mount console.log is executed two times (check logs at bottom right):

Reproduction:
https://codesandbox.io/s/sweet-roentgen-v2kdl6?file=/src/App.js

Is it expected? Can I make it to execute only one time on mount?

PS: sometimes console.log is executed only once but most of the time it's executed twice

This is probably because you're running React in strict mode.
