True Crime: Type Safety Edition

Content Typescript type system sigsegmeme Python type system

The beautiful irony of throwing an AssertionError with the message "Unreachable code reached" is just *chef's kiss*. It's the programming equivalent of installing a security camera inside a black hole. You're basically telling the compiler "this code will never execute" and then writing an error message for when it does execute. The cosmic paradox of defensive programming at its finest! This is the senior developer's version of "trust no one, not even yourself." They've been burned too many times by "impossible" edge cases showing up in production at 3 AM.

When you finally convince your team to use TypeScript for type safety, but then discover your codebase is just a sea of any types everywhere. The whole point of TypeScript was to avoid this exact situation! It's like buying a Ferrari and then towing it behind a bicycle. Congrats, you've successfully implemented JavaScript with extra steps.

The subtle yet profound difference between null != domain and domain != null is perfectly captured here! The first check (happy face) follows the defensive programming principle of putting the constant first to avoid accidental assignments. Meanwhile, the second approach (angry face) risks the dreaded NullPointerException if someone mistakenly types = instead of != . This tiny syntax choice literally determines whether your code review ends with approvals or a 47-comment thread about proper null checking conventions. The facial expressions perfectly match the emotions of discovering which style your codebase has standardized on!

Friend: "I love TypeScript!" Me: *shows them actual TypeScript code with VSCode extension development* Friend: *visible confusion* Turns out they just love the idea of type safety, not the existential crisis of configuring tsconfig.json and wrestling with extension APIs. It's like saying you love cooking but fainting at the sight of a raw chicken. The expectation vs. reality gap is wider than my monitor bezels.
