title: Concat string in the middle of another String, skipping the last
body: <p>I want to transform this String "23 março 2019" into "23 de março de 2019".</p>
  
  <p>I did the way below and it works, but I have to type a lot to get rid of the 'in case first' "de". </p>
  
  <pre><code>String strDate = splitted[0];
          var fullDate = strDate
              .split(" ")
              .map((s) =&gt; " de " + s)
              .join()
              .trim()
              .split(' ')
              .skip(1)
              .join(' ');
  </code></pre>
  
  <p>Is there a way to simplify this expression maybe doing the equivalent to (skipLast function doesn't exits):</p>
  
  <pre><code>var fdate = strDate.split(" ").map((s) =&gt; s+" de ").skipLast().join();
  </code></pre>
