Unnecessary Line of Code

[mgovilla]

In server.js there is an unnecessary line of code at 22:

a1-gettingstarted/server.js

Lines 20 to 25 in e5f841d

	const sendFile = function( response, filename ) {
	fs.readFile( filename, function( err, content ) {
	file = content
	response.end( content, 'utf-8' )
	})
	}

file is not used again after this assignment which makes it safe to delete
