im looking iterate through next object , determine index item-2 (or other string) belongs too. in case expect index [0] , case of item-2 [1]

the string im looking determine index for, exist first object index - in below illustration item-1 , item-2

var products = [ ["item-1", "image1.png", "image2.png", "image3.png" ], ["item-2", "image1.png", "image2.png" ] ];
