indexOf() -- given a String and an array of Strings, return the index of that String in the array. If the String is not in the array, or the array is empty, -1 should be returned. If the String occurs more than once in the array, return the index of the first occurrence of that String. indexOf("a", ["b", "a", "a"]) → 1 indexOf("b", ["b", "a", "a"]) → 0 indexOf("x", ["b", "a", "t"]) → -1 ...Save, Compile, Run (ctrl-enter) |
