title: Splitting on first occurrence
body: <p>What would be the best way to split a string on the first occurrence of a delimiter?</p>
  
  <p>For example:</p>
  
  <pre><code>"123mango abcd mango kiwi peach"
  </code></pre>
  
  <p>splitting on the first <code>mango</code> to get:</p>
  
  <pre><code>"abcd mango kiwi peach"
  </code></pre>
