React HOC (Higher Order Component) Example
/* HOC fundamentally is just a function that accepts a Component and returns a Component:
(component) => {return componentOnSteroids; } or just component => componentOnSteroids;
Let's assume we want to wrap our components in another component that is used for debugging purposes,
it just wraps them in a DIV with "debug class on it".
Below ComponentToDebug is a React component.

//HOC using Class

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just
