title: Do unnecessary curly braces reduce performance?
body: <p>After recently encountering this while programming, I have been wondering about this. Below are 2 snippets which are both legal and compile. Specifically, my question is this.. in the second case, do the brackets make the program slower? Also why is this allowed?</p>
  
  <p><strong>1st case:</strong></p>
  
  <pre><code>if (statement)
  {
   // do something
  }
  </code></pre>
  
  <p><strong>2nd case:</strong> </p>
  
  <pre><code>{
      if (statement)
      {
          // do something
      }
  }
  </code></pre>
  
  <p>Additionally what if I had something like the code below.. Is the runtime the same as just calling function X without any of the curly brackets. </p>
  
  <pre><code>{
    {
      {
        // call function X
      }
    }
  }
  </code></pre>
