Code Review Checklist

Code Review Checklist

General

  • Does the code work? Does it perform its intended function, the logic is correct etc.
  • Is all the code easily understood?
  • Does it conform to your agreed coding conventions? These will usually cover location of braces, variable and function names, line length, indentations, formatting, and comments.
  • Is there any redundant or duplicate code?
  • Is the code as modular as possible?
  • Can any global variables be replaced?
