Pattern: digit/string scan

Move: Convert number to string → count "0" → if count is odd, increment answer.

Mistake to avoid: Do not overthink. This is just scan/count/rule.

Setup

SVN is hosted at svn.domain.com.au.
SVN is accessible via http (other protocols should work).
GitLab is hosted at git.domain.com.au and:

Javascript Design Patterns

	I have a keen interest in design patterns as I try to reshape my interst to writing code for day to day and rather, doing
	architecture, code reviews, business meetings, etc. This means I must understand design patterns as this would also help me
	to understand how to read code.

	Of My head the following patterns are what I know:

	1. Singleton
	2. Factory
	3. Facade
	4.
