title: String declaration by character "A" + "B" vs "AB"
body: <p>Instead of</p>
  
  <pre><code>string someString = "AB";
  </code></pre>
  
  <p>I stumbled upon</p>
  
  <pre><code>string someString = "A" + "B";
  </code></pre>
  
  <p>Is there any technical explanation which renders the second way more advantageous?</p>
