1. Function 3: Insert delimiter and join content of array as one string
2. Write a function that accepts three arguments (an array, delimiter, and a number). The function would join content of the array to form a string, inserting the delimiter after every nth element of the array and displays resulting string in console:

functionName([0, 2, Hello, 7, TO, ---], +, 3); // would produce following message in console:

1. 02Hello+7TO---+
2. PLEASE EXPLAIN THE CODE THANK YOU
