title: Difference between const and readonly in typescript
body: <p>Constant vs readonly in typescript</p>
  
  <p>Declaring a variable as <code>readonly</code> will not allow us to override even if they are public properties.</p>
  
  <p>How const behaves,</p>
  
  <pre><code>const SOME_VARIABLE:number = 10;
  </code></pre>
  
  <p>If I override its value, how will it work?</p>
