Just started watching your guide of making a 2d game in unity and its so cool. After that tutorial, what would you suggest to learn about Unity because I really like the 2D game aspect

[NijatNiyazov]

Yeah. This approach does same too
[...new Array(12)].map((_, i) => <Box key={i} />)

I’m sorry if this question is a bit vague (I’m not a React developer), but doesn’t React have for or while loops?

Lol. Devs who actually repeat the components are going to feel roasted 😅

Second implemention wastes memory by allocating an array of undefined elements, the map function then creates a new array of Box elements. Baffling that this is considered "best practices"
