Check your variable declaration of banners and products It should be like this:- const[banners,setBannerd]=usestate([]); CHECK YOUR USESTATE HAVE YOU PASSED EMPTY ARRAY OR NOT.

forEach only works with an array. You are getting error because your banners or products is not an array somehow you made a mistake in initializing those variables as array
