    Array join method Redirect 1


    The join() method joins all elements of an array into a string.


    str = arr.join(separator)


    Specifies a string to separate each element of the array. The separator is converted to a string if necessary. If omitted, the array elements are separated with a comma.


    The string conversions of all array elements are joined into one string.


    Example: Joining an array three different ways

    The following example creates an array, a, with three elements, then joins the array three times: using the default separator, then a comma and a space, and then a plus.

    var a = new Array("Wind","Rain","Fire");
    var myVar1 = a.join();      // assigns "Wind,Rain,Fire" to myVar1
    var myVar2 = a.join(", ");  // assigns "Wind, Rain, Fire" to myVar2
    var myVar3 = a.join(" + "); // assigns "Wind + Rain + Fire" to myVar3
