Code Smell 74 - Empty Lines

Code Smell 74 - Empty Lines

Play this article

Breaking the code to favor readability asks for refactor.

TL;DR Don't add empty lines to your methods. Extract them!


  • Readability

  • Kiss

  • Low Reuse


  1. Extract Method

  2. Refactor

  3. Remove unneeded lines.

Sample Code



function translateFile() {
    //A lot of lines more

    //Empty space to pause definition    

    //Yet Another empty space
    //A lot of more lines

function translateFile() {


This is a policy smell. Every linter can detect blank lines and warn us.


  • Readability

  • Long Methods


Empty lines are harmless, but show us an opportunity to break the code into small steps.

If you break your code with comments, it is also a code smell asking for a refactor.

It’s OK to figure out murder mysteries, but you shouldn’t need to figure out code. You should be able to read it.
