title: filter an array of objects based on specifc attributes
body: <p>I have an array of displayed columns : </p>
  
  <pre><code>displayedColumns = ['CompanyName','Ticker', 'Id', 'Name', 'Date', 
        'Spot', 'PreviousTradeDate', 'PreviousSpot', 'FPrice', 'Status']
  </code></pre>
  
  <p>and an array of objects (retrieved from db,which contains more than the displayed columns attributes  ) : </p>
  
  <pre><code> data = [ {CompanyName = "..." Ticker = "..." other attributes........}
  {.......} ]
  </code></pre>
  
  <p>I am having trouble with filtering the <code>data</code> array to show only the <code>displayed columns</code> attributes and their values (without the other attributes)</p>
  
  <p>didn't quite understand how to do it with <code>map()</code> function when I want to filter by more than one value</p>
  
  <p>thanks a lot</p>
