Those who don’t know 
One-Line Flow:
TypeScript just did the impossible — it beat Python and JavaScript to become GitHub’s favorite kid in 2025.
What Went Down
GitHub dropped its yearly report — and boom:
TypeScript is now the #1 language.
- 2.63 million devs use it (that’s 42 k more than Python).
- It grew 66% in a year.
The Top 5 Languages:
TypeScript
Python
JavaScript
Java
C#
Biggest Year Ever
GitHub’s 2025 stats are wild:
- 121 million new repos this year.
- 5.3 million were TypeScript.
- 1.1 million public repos now use AI SDKs.
- 693 k of those came just this year.
- 518 million pull requests merged.
- 80% of new devs turned on Copilot in their first week.
GitHub’s basically turning into an AI-powered playground.
Why Everyone Switched
Every major framework starts with TypeScript now —
Next.js 15, Astro 3, SvelteKit 2, Angular 18, Remix, and more.
TypeScript stops dumb bugs before they break things.
It catches 94% of AI code errors before launch.
And with tools like Vite, Bun, and ts-node, setup takes seconds.
So What? — How the TypeScript Hype Actually Pays Rent, Dumb Bitch 
- The Freelance Filter
Everyone’s moving projects to TypeScript → Upwork and Fiverr gigs now quietly add “TS required.”
Translation: learn it now, charge a “2025 ready” premium later.
Example: Someone just made $1.2k fixing AI-generated TS bugs from ChatGPT scripts that couldn’t even run “npm start.”
- The API Broker Angle
With AI tools spitting buggy JS, clean TypeScript APIs become gold.
Package your stable scripts, sell them as “AI-safe components.”
Example: A dev sells pre-typed “Stripe + OpenAI” wrappers for $49 — basically reusable AI plumbing.
- The Dev Stack Arbitrage
Offer “Convert your JS mess to TS” services — one-click refactors for lazy startups drowning in spaghetti code.
Example: A guy on IndieHackers turned his TS-conversion script into a $30/mo SaaS with zero marketing.
- The Framework Piggyback
New frameworks like SvelteKit 2 and Qwik default to TypeScript.
Make templates, starter packs, or boilerplate bundles and sell them cheap-fast-scalable.
Example: One dev made $700 in a week selling a “TypeScript SaaS Starter Kit” built with Astro 3.
- The AI-Proof Certifier
LLMs generate garbage — TS catches it.
Offer audits: “I’ll run your AI-written code through TypeScript and make it production-safe.”
Example: A freelancer branded it “AI Detox for Code” — billed $150/hour fixing Copilot hallucinations.
- The Learning Loop
Create short “Crash-to-Cash TypeScript Bootcamps” for beginners.
Everyone wants to learn it but hates reading docs — spoon-feed, charge micro-payments.
Example: Someone made $900/month on Gumroad from 10-minute “TypeScript for Dummies Who Code” videos.
- The Plugin Farm
Copilot, Cursor, and VS Code extensions thrive on TypeScript.
Build tiny plugins that save 2 clicks — sell, license, or open-source for Patreon tips.
Example: A dev made a $3k side income with a VS Code plugin that just color-codes TODOs by urgency.
- The Hiring Lens
Companies now quietly prefer TS-fluent devs.
Run a tiny recruiting side-agency or AI resume screener for TS roles — middleman the talent flow.
Example: One hacker built a bot that matches TS freelancers with startups — takes a 10% cut, sleeps fine.
- The Ghost Maintainer Model
Many open-source TS projects grow fast but lack maintainers.
Join, patch, gain visibility — then monetize via sponsorships, premium forks, or SaaS add-ons.
Example: A maintainer of an abandoned “TypeScript CSV Parser” got $2k/month in GitHub sponsors after cleanup.
- The Ripple Trade
Languages drive tool demand.
TS dominance = spike in testing tools, type validators, schema generators.
Find early-stage GitHub tools solving these gaps → invest time, fork early, brand smart.
Example: The first dev who forked a TS-based API validator now licenses it to 6 AI startups — easy passive income.
TypeScript isn’t just code anymore — it’s the new plumbing of AI-powered web dev. And plumbers? They always get paid.
Python Still Fighting
Python’s not dead — it still rules AI projects.
There are 582 k AI-tagged repos, up 50% from last year.
But the JS + TS combo now runs the web.
Small Print
GitHub ranks by active contributors, not by total code.
So yeah — other charts (like TIOBE) still show Python #1.
Different game, different rules.
Up-and-Coming Languages
- Luau (from Roblox) grew 194%.
- Typst (a LaTeX rival) grew 108%.
Quiet now, booming soon.
Final Thought
TypeScript didn’t just win — it leveled up.
While everyone chased AI, it became the safety net for AI-written code.
2025’s rule: if it’s not typed, it’s risky.
