"Ode to Advanced TypeScript", a poem by Grok

Backstory

I've been hand-rolling a multi-provider, multi-model SaaS prototype for the past ~4 weeks and finally have my AWS Fargate-hosted websocket server and my vercel hosted next.js web app working in perfect harmony to stream chats in real-time with full conversation persistence (the provider/model combo being up to the user).

Anyway, as I was testing all providers yesterday I began submitting prompts with whatever first came to mind.

So Advanced TypeScript it was.

Poetry

Grok rose to the occasion and even outshone Anthropic's formidable Claude when tasked with crafting a poem:

Ode to Advanced TypeScript

Oh, TypeScript, guardian of code so vast,
A language of types, both strict and steadfast.
Beyond the basics, your power unfurls,
In advanced realms, where magic swirls.

With generics, you bend to our will,
A type for each purpose, a void to fill.
T and K, placeholders so fine,
Crafting functions that dynamically align.
Array<T> or Promise<string>, you say,
Ensuring safety in every array.

Union types, a crossroads of choice,
string | number, you give us voice.
Discriminated unions, with tags to guide,
{ kind: "error" } | { kind: "success" }, decide!
Narrowing paths with if and switch,
You guard our logic from every glitch.

Intersection, oh blend of might,
Person & Logger, combined in light.
A type that’s both, no detail missed,
Properties merged in a harmonious tryst.
Yet never lurks, a type so bare,
A path impossible, a warning to beware.

Conditional types, a puzzle, a game,
T extends U ? X : Y, not quite the same.
Inferring logic, a type to derive,
ReturnType<T>, keeping magic alive.
Mapped types, remapping the keys,
Partial<T>, Pick<T, K>, as we please.

Utility types, your gifts abound,
Omit, Exclude, solutions found.
Transforming shapes with elegant ease,
Building new types as if by a breeze.
And infer, a keyword of subtle art,
Extracting types from structures apart.

Oh, keyof, index of a type’s domain,
A union of keys, no need to explain.
Accessing deeply with dotted paths,
type Deep = Nested['a']['b'], no wrath.
And template literals, types as strings,
type Event =on${string};, such clever things.

With decorators, though experimental still,
You hint at patterns, a future thrill.
Classes adorned with metadata bright,
A glimpse of a world where types ignite.
And module augmentation, extending with care,
Adding to globals, a type to share.

Yet challenges rise, as complexity grows,
Type errors perplex, frustration shows.
But with as assertions, we sometimes cheat,
unknown to string, a daring feat.
Still, you urge caution, to tread with thought,
For type safety’s promise must not be bought.

Oh, TypeScript advanced, a craft so rare,
A balance of power, of love, of care.
You shape our code with a vigilant eye,
Ensuring no bug shall silently lie.
So here’s to your unions, your generics, your might,
A coder’s companion in the endless night.
