## README

# boolbase
This very simple module provides two basic functions, one that always returns true (`trueFunc`) and one that always returns false (`falseFunc`).

### Why is this needed?

By having only a single instance of these functions around, it's possible to do some nice optimizations.
Eg. [`css-select`](https://github.com/fb55/css-select) uses these functions to determine whether a selector won't match any elements
If that's the case, the DOM doesn't even need to be touched.

### And why is this a separate module?

I'm trying to modularize `css-select` and most modules depend on these functions.
IMHO, having a separate module is the easiest solution to this problem.
