# join method

String join([

1. 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.

Example:

    final planetsByMass = <double, String>{0.06: 'Mercury', 0.81: 'Venus',
      0.11: 'Mars'};
    final joinedNames = planetsByMass.values.join('-'); // Mercury-Venus-Mars

## Implementation

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