Outsourcing Your TypeScript Migration To The Real Senior Engineer

Asking an AI to convert your entire JavaScript codebase to TypeScript with "make no mistakes" is like asking a genie for unlimited wishes. Sure, Claude's sitting there all innocent with its little cursor blinking, but behind that interface is the digital equivalent of sweating profusely. Converting JS to TS isn't just adding some colons and angle brackets—it's archaeological excavation where half the artifacts are actually landmines. The real comedy starts when you merge that PR and suddenly your build pipeline looks like a crime scene investigation.

Your IDE is like that overeager ensign who reports problems before you've even had a chance to finish typing. Create a variable, look away for half a second, and suddenly your editor's throwing red squiggly lines everywhere like there's a warp core breach. Listen, computer—I'm giving her all she's got. Some of us need more than 3 milliseconds between declaration and implementation.

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.

The emotional trauma of diving back into TypeScript after swimming in the lawless waters of JavaScript is just too real. It's like going from a world where you can declare variables as whatever the hell you want, to suddenly having a strict parent checking your homework and screaming "TYPE ERROR" at every turn. That fetal position is the universal developer stance for "I've seen things in that legacy codebase that cannot be unseen." The sweet structure of TypeScript feels like both salvation and punishment after you've been living like a code bandit for too long.

First panel: JavaScript behaving like a normal language where string + string = concatenated string. Second panel: JavaScript on crack where '2'+'2' = 100 and "Hello"+2 = "llo". The true horror of JS type coercion in its natural habitat. What kind of sadistic language designer thought "yes, let's make + sometimes concatenate and sometimes convert strings to numbers based on my mood today"? This is why senior devs have that thousand-yard stare during code reviews.
