title: JavaScript regex to validate an address
body: <p>I would like to validate residence address in the JavaScript using regex, but I dont know much about the regex, what I have tried is to build my own regex (<code>/^[a-zA-Z\s](\d)?$/</code>) but it doesn't seem to work properly.</p>
  
  <p>What I want to achieve is to allow letters, spaces and at least one digit (thats required) and also there should be a possibility to insert the slash <code>/</code> but it shouldnt be required.</p>
  
  <p>Could anyone help me with that?</p>
