This very simple module provides two basic functions, one that always returns true (trueFunc) and one that always returns false (falseFunc).
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.
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.
Lodash is a comprehensive utility library that offers a wide range of functions for manipulating and working with data. It includes methods like _.constant which can be used to create functions that return the same value. Lodash is much larger and more feature-rich compared to the minimalistic boolbase.
Underscore is another utility library similar to Lodash, providing a range of functions for working with arrays, objects, and functions. It includes the _.constant function for creating functions that return a specific value. Like Lodash, it is more extensive than boolbase.
Ramda is a functional programming utility library that emphasizes a purer functional style. It includes R.always, a function that returns a function that always returns the same value. Ramda offers a more functional approach and has a broader set of features compared to boolbase.
