# join method

String join ([String separator = "" ])
override

Converts each element to a String and concatenates the strings.

Iterates through elements of this iterable, converts each one to a String by calling Object.toString, and then concatenates the strings, with the `separator` string interleaved between the elements.

## Implementation

    String join([String separator = ""]) {
      if (length == 0) return "";
      StringBuffer buffer = StringBuffer()..writeAll(this, separator);
      return buffer.toString();
    }
