Atom text editor remove trailing whitespace on save

I use Sublime text. Now I am trying Atom. When I save any file in sublime text it does not include any trailing blank line. But saving any file in Atom leaves a trailing blank line. How do I force Atom not to leave trailing white spaces?

Answer

Under your Atom Preferences go to Packages tab and search for whitespace. Click on the whitespace package and uncheck Ensure Single Trailing Newline option
