• Arr. indexOf ('Orange ') outputs 0 because 'Orange' is the 0th element of the array, matches and returns a subscript.
• Arr. indexOf ('O') Output-1 because this method will not re-Execute indexOf matching on the basis of each element.
• Arr. indexOf ('200') Outputs 1 because this method matches the table from the ground up until the first array element is matched, instead of returning all matched subscript.
