I have a function component, and I want to force it to re-render.

How can I do so?
Since there\'s no instance this, I cannot call this.forceU

Disclaimer: NOT AN ANSWER TO THE PROBLEM.

Leaving an Important note here:

If you are trying to forceupdate a stateless component, chances are there is something wrong with your design.

Consider the following cases:

1. Pass a setter (setState) to a child component that can change state and cause the parent component to re-render.
2. Consider lifting state up
3. Consider putting that state in your Redux store, that can automatically force a re-render on connected components.
