Patterns need comments/README.md

[kushal-g]

I wanted to learn about various javascript patterns and this repository seemed to be the perfect place to start because of having so many patterns at a single place. However, due to the lack of comments and explanation, beginners like me would not be able to understand very well what a pattern is trying to achieve exactly.

It would be great if each pattern has a README to explain exactly what problem it is trying to solve and how it is doing so.
