I'm unfamiliar with React, but I'm guessing you're missing the key property on #project-section

Thanks it does work But I have 2 more divs but it doesn't ask for key , but why it asks for this main div ?

Jochem•6mo ago

because it's the direct descendent of the loop it needs to be able to reference the main descendent easily
