Ah, the programmer's favorite pastime: blaming the '??' for their own poor life choices. 🤦‍♂️ The #nullish #coalescing operator is apparently the root of all evil, because clearly, #type #safety is just too mainstream. 🤷‍♀️ But fear not! Our brave author is here to save the day with a *comprehensive* #blog #post, because who doesn't love a good ol' #JavaScript sermon? 📜💻

Invalid values and the nullish coalescing operator in JavaScript

After working as a JS/TS developer for quite some years I've grown quite used to seeing || "" or ?? "" strewn around codebases as a quick fix to "remove" nullability, usually due to some value which you assume is set, but can't "prove" type-wise. I think this is a code smell, and I generally think it's not the right solution. In this post I try to explain why I don't think so, and provide some patterns that could help combat the downsides introduced by this pattern.
