npm install null
Null all of the things! This package was originally created as a joke, but hey now it actually does something non-trivial.
If you ever use
null for logic tests, you can try using a
Symbol instead via the NullRef library provided by this package.
This package provides for a
NULL constant that is a Symbol from the Global Symbol Registry, as well as convenience methods for testing, casting, and comparing values.
Require and reference what you need:
const nullref = require('null'); // note that the variable name should not be null, here we use nullref const nulltest = nullref.lib; // load the full library of convenience features const isNull = nullref.isNull // or just load the main ones you want (checks for null or NULL) const isNullRef = nullref.isNullRef // checks for NULL only const NULL = nullref(); // NULL symbol instance (singleton);
Consume and use as needed.
let x = null; //returns true if x is null or NULL if( nulltest.is(x) ) //do something if( isNull(x) ) // same as above //cast a variable to NULL if it is null or NULL, otherwise it returns itself if( NULL === nulltest.to(x) ) // do something
