3 Quick Tips for Improving Code Quality

Improving code quality and preventing unnecessary errors is really simple. In this episode I go over 3 simple things you can do to improve the code you write.

1. Using guards, 2. Never trust data, 3. Keep it simple

Good video. I've found to be difficult for developers to embrace this simple rules. Mainly the "Never trust data". Most times we manage all data and we assume that, if we reach this point, then the data has to be correct. It's never like that.

Wow this good lesson on writing quality code. You can never really assume your user is going to insert proper data. They may even do it mistakenly.  Thanks for the lesson! :-)

Yes, simple code is easy to understand and maintain.

How do you have the numbers of references above the method?

4:09 Nein! Nein! Nein! Nein! Nein! Nein! Absolutely don't do that.
"something".Equals(r.Value);
The string literal "something" is guaranteed not to be null and Equals will check for nulls internally.

NEVER use guards! Document the preconditions and move the responsibility to the client using your code. This way your code is simpler and you avoid that guards will be implemented redundantly in chains of method calls.
