title: Regex: must start with a letter or a number but the rest can be anything
body: <p>I am trying to construct a pattern in order to use in validation.</p>
  
  <p>My goal is to have the first character to be a letter or a number, the rest anyhing.</p>
  
  <p>i.ex:</p>
  
  <ol>
  <li>A'r4nd0m!</li>
  <li>9!h3ll0.</li>
  <li>b1llin6s</li>
  </ol>
  
  <p>I thought of: <code>[a-zA-Z0-9_/][.*]++</code></p>
  
  <p>What would be the solution?</p>
  
  <p>Thank you!</p>
