title: Syntax error: Unexpected token equal sign '='
body: <p>i'm trying to build a form on react for a home assignment,
  i'm trying to follow <a href="https://www.youtube.com/watch?v=qH4pJISKeoI" rel="nofollow noreferrer">this</a>! 
   tutorial 
   i get this error i couldnt solve nor find a solution</p>
  
  <p>my first attempt:</p>
  
  <pre><code>export default class Form extends React.Component{
      state = {
          firstName = "",
          lastName = "",
          email = "",
          phone = "",
      }
  
  </code></pre>
  
  <p>my second attempt</p>
  
  <pre><code>export default class Form extends React.Component{
      constructor(props){
          super(props);
          this.state = {
              firstName = "",
              lastName = "",
              email = "",
              phone = "",
          }
      }
  </code></pre>
  
  <p>they both end up with this error:
  Syntax error: Unexpected token
  when the arrow points to the equal sign under firstName = ""</p>
  
  <p>thanks</p>
