title: Why React Hook useState uses const and not let
body: <p>The standard way to use a React useState Hook is the following:</p>
  
  <pre><code>const [count, setCount] = useState(0);
  </code></pre>
  
  <p>However this <code>const count</code> variable is clearly going to be reassigned to a different primitive value.</p>
  
  <p>Why then is the variable not defined as <code>let count</code>?</p>
