title: ReactJS - Cannot restrict user input to letters only
body: <p>I'm trying to restrict user input to letters only but for some reason it's not working. I'm very new to ReactJS so maybe my problem lies here somewhere. This is what I've got so far:</p>
  
  <pre><code>&lt;input type="text" pattern="[a-zA-Z]*" placeholder="Add Skill" onChange={this.updateField} /&gt;
  </code></pre>
  
  <p>type="text" and pattern seem not to work in this case.</p>
  
  <p>Thanks in advance!</p>
