Debugging

Debugging JavaScript Applications

A practical distillation for Fullstack Academy students

Faults in computer problems were theorized as far back as 1843, when Ada Lovelace noted of Babbage's Analytical Engine, "Granted that the actual mechanism is unerring in its processes, the cards may give it wrong orders." Almost 160 years later, NIST reported that software errors cost the US $59 billion annually. Clearly, some of the cards are wrong. However, unlike Grace Hopper's famous moth, most of the time the culprit is ourselves.

Debugging is a sanitization procedure consisting of:

  • Preventing bugs in the first place, through good practices and assistive tooling.
  • Detecting bugs when they first arise, through proper error handling and testing.

Summary of 'Clean code' by Robert C. Martin

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.


General rules

  1. Follow standard conventions.
  2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
  3. Boy scout rule. Leave the campground cleaner than you found it.
  4. Always find root cause. Always look for the root cause of a problem.

Design rules

CSS best practices

What CSS best practices should I follow ?

HTML best practices Depends. How far down the rabbit hole do you want to go ?

Just need something to look good : use a frontend framework like foundation or bootstrap, won't learn much about CSS. Short list of Front End Frameworks

Surface level : work general to specific. Comment the sections of the CSS. Use a reset or normalizer. Work on patterns, use classes over IDs for reuse. CSS Resets - includes normalize.css Don't have links for the other parts. see below

Little bit deeper : Look into BEM or OOCSS. Those stand for Block Element Modifier and Object Oriented CSS. Two popular methodologies for CSS. Also SMACSS.
