# `first` New in version 1.12.2: The `first` filter was added in Twig 1.12.2. The `first` filter returns the first "element" of a sequence, a mapping, ora string: <table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre>1 2 3 4 5 6 7 8</pre></div></td><td class="code"><div class="highlight"><pre>{{ [1, 2, 3, 4]|first }} {# outputs 1 #} {{ { a: 1, b: 2, c: 3, d: 4 }|first }} {# outputs 1 #} {{ '1234'|first }} {# outputs 1 #} </pre></div></td></tr></table> Note It also works with objects implementing the [Traversable](http://php.net/manual/en/class.traversable.php) [http://php.net/manual/en/class.traversable.php] interface.
