Boolean Algebra in a nutshell for JS/TS programmers

There are a lot of strategies that you will hear about in the Javascript community for keeping your conditionals from becoming a tangled mess. This isn't like them. This is someting different. MATH! Boolean Algebra to be exact. I use it all the time to simplify complex conditionals. There are two things that you need to know: de Morgan's Theorem, and Karnaugh (pronounced CAR-no) Maps. (Don't worry, there is no test)

de Morgan's Theorem

De Morgan's Theorem is great distributing nots (!), and for when you want to convert an && to an ||, or back. This is it:

 !(A &amp;&amp; B) = !A || !B
