Post funny things about programming here! (Or just rant about your favourite programming language.)
The way I use it is 'undefined' is literally undefined (not set), but null means no value - explicitly.
I used to ban
null
usages with ESLint rules for this exact reason. If it’s there use a value, if not useundefined
Except you can define a value with undefined and accessing that value will have different behavior than attempting to access an undefined value.
