Discussion on: 5 ways to refactor if/else statements in JS functions

Tip: instead of something === undefined && something === null you can write something == null and it matches both undefined and null, and only them.

I find it the only valid case to use == over ===.

That's true, but oftentimes you have a linter which forces to use "eqeqeq"

Only if you have had someone strongly opinioned setting it up :) And even then you have the null: ignore option for it.
