Constants Background
Constants Background
@lou.codes/constants is just a few common constants used across my projects.
Why
I had a bunch of Object.create(null) and Object.freeze(Object.create(null))
for immutable empty objects only used for spreading. Also used {} sometimes,
but the issue with it is that syntactically it becomes hard to read after a
while, and having that on a constant make sense. Same for stuff like [] and
"", where you can’t tell if that’s accessing a property, or creating a new
thing.
Long story short, is like the rule against “magic numbers”, but for empty objects, arrays and strings.
How
I started using create-package, and from there I just exported the constants I needed, removed tests because is just values, and then I just went to all the places where this values were duplicated and replaced them with the new constants.
Where
It’s being used by pretty much all my libraries now.
