Theory

This tool has been designed to take an input condition, analyze it and produce a new condition that would yield an absolute opposite result. This is illustrated by the following example:

Properties	Original condition	Result	Inverted condition	Result
dog = true, cat = false	dog && cat	false	!dog \| \| !cat	true
dog = 3, cat = 2	dog < cat	false	dog >= cat	true

Condition Inverter supports all modern progrogramming languages and frameworks. This includes technologies that have been ranked as the most popular on the Stack Overflow Developer Survey.
Disclaimer - this tool does not currently support query, shell scripting or assembly based languages.
