title: Which has better performance: test != null or null != test
body: <p>Consider the following two lines of code</p>
  
  <pre><code>if (test ! = null)
  </code></pre>
  
  <p>and </p>
  
  <pre><code>if (null != test)
  </code></pre>
  
  <p>Is there is any difference in above two statements, performance wise? I have seen many people using the later and when questioned they say its a best practice with no solid reason.</p>
