Synopsis

.join(separator
)
Arguments
-
separator
An optional character or string used to separate one element of the array from the next in the returned string. If this argument is omitted, a comma is used.
Returns
The string that results from converting each element of
array
to a string and then
concatenating them together, with the
separator
string between
elements.
Description
join( )
converts each
element of an array to a string and then concatenates those strings,
inserting the specified separator
string
between the elements. It returns the resulting string.
You can perform a conversion in the opposite
direction—splitting a string into array elements—with the split( )
method of the String object. See
String.split( )
for
details.
Example
a = new Array(1, 2, 3, "testing"); s = a.join("+"); // s is the string "1+2+3+testing"
