Posted By: Anonymous Given 2 arrays of different length: const vals = ["A", "B", "C", "D", "E", "F", "G", "H", "I"]; const test = ["B", "D", "E", "H"]; I need a new array containing the values in ‘vals’ that are in ‘test’ and their corresponding index as an object like result = [{1:"B"}, {3:"D"}, {4:"E"}, …
