title: Should I include the argument even though it is not needed
body: <p>Which one is a better way to write codes ?</p>
  
  <p>1st version:</p>
  
  <pre><code>let displayTodos = (item) =&gt; console.log('My todo list:', todo)
  displayTodos()
  </code></pre>
  
  <p>2nd version</p>
  
  <pre><code>let displayTodos = () =&gt; console.log('My todo list:', todo)
  displayTodos()
  </code></pre>
  
  <p>Both will give me the same result but which one is the accepted standard to write a simple function ?</p>
