boolbase
This very simple module provides two basic functions, one that always returns true (trueFunc
) and one that always returns false (falseFunc
).
WTF?
By having only a single instance of these functions around, it's possible to do some nice optimizations. Eg. 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.
