var $export   = require('./_export')

// fallback for not array-like strings
$export($export.P + $export.F * (require('./_iobject') != Object || !require('./_strict-method')(arrayJoin)), 'Array', {
  join: function join(separator){
    return arrayJoin.call(toIObject(this), separator === undefined ? ',' : separator);
