You’ve got most likely seen the damning debate about whether or not AI has made programming out of date. The development of “vibe coding,” the place folks launch apps at evening with the assistance of AI, has everybody from tech buddies to aunts asking: Do I have to study one other programming language?
At Codecademy, we’ve got at all times maintained that AI is not going to disrupt programming ever since ChatGPT debuted in 2022. Even with refined AI assistants and an important environment, understanding the code is important to directing AI instruments, validating their output, and shaping the programs that matter within the area.
The selection of programming language is extra necessary than ever earlier than, and actual builders are voting with their keyboards. TypeScript is the highest programming language of 2025, in response to GitHub’s newly released Octoverse 2025 reporttracks the actions and utilization patterns of over 180 million builders.
So what makes this superset of JavaScript so common with folks on GitHub proper now? Learn this text to find out how TypeScript works, why it is one of the best language for AI initiatives, and how one can begin studying TypeScript at any stage as we speak.

TypeScript has turn out to be the most well-liked language on GitHub
In August 2025, TypeScript overtook each Python and JavaScript to turn out to be essentially the most used programming language on GitHub, the main on-line growth surroundings. GitHub known as it “essentially the most important language change in additional than a decade.”
Take a more in-depth have a look at TypeScript statistics from the brand new GitHub report.
- Over 2.6 million month-to-month contributors create TypeScript
- 66% year-over-year development (1 million+ new contributors in 1 yr)
- For the primary time in GitHub historical past, typed JavaScript variants prime the rankings.
Stack Overflow’s 2025 Developer Survey It confirms this hype about TypeScript. After they requested builders, “In what programming, scripting, and markup languages have you ever executed important growth work previously yr?”, this is what they discovered.
- 66% stated JavaScript
- 43.6% stated TypeScript
Virtually half of all builders already use TypeScript extensively. Whether or not you have a look at GitHub utilization information or Stack Overflow analysis, the story is identical. TypeScript went from being “common” to being “important.”
What’s TypeScript? What’s it used for?
TypeScript is just not one other language that competes with JavaScript. TypeScript is a layer on prime of JavaScript that provides extra performance and compiles into common JavaScript that runs within the browser.
Particularly, TypeScript provides static typing to JavaScript. It is a fancy means of claiming that you just declare what sort of information you are working with (numbers, strings, objects, and so on.) earlier than you utilize it.
Here is a easy instance. In JavaScript you may write it like this:
javascript
perform greet(title) {
return "Good day, " + title;
} In TypeScript, you’ll write it like this:
typescript
perform greet(title: string): string {
return "Good day, " + title;
} see them : string addition? These are kind annotations. These inform TypeScript (and anybody studying your code) that the title must be a string, and the perform returns a string.
Here is why that is necessary: Debugging JavaScript was time consuming and errors had been occurring solely when the code was executed. TypeScript modified this by detecting errors like passing the fallacious variable kind earlier than execution. Its kind system helps discover bugs, make clear construction, and assist refactoring, which is crucial for big codebases.
TypeScript can run wherever JavaScript runs. So you may mainly run it wherever.
- Entrance-end internet apps (React, Angular, Vue initiatives)
- Full-stack purposes (Subsequent.js, Remix)
- Cellular app (React Native)
- Backend server (Node.js, Specific)
- Desktop utility (Electron)
- APIs and microservices
Why is TypeScript an excellent language for AI?
Typed languages are the only option for AI programs. Sort annotations assist each LLMs and builders perceive context and catch errors earlier than they turn out to be issues.
TypeScript has turn out to be an integral a part of AI growth as builders are actually constructing with AI coding assistants like GitHub Copilot and Cursor. When AI generates code, TypeScript instantly flags kind mismatches, undefined variables, and invalid perform signatures. 2025 study We discovered that 94% of errors generated by LLM in code are type-related. TypeScript robotically catches these LLM errors earlier than the code is executed, making a suggestions loop that makes AI-assisted growth considerably sooner and safer.
To be clear, Python nonetheless dominates core AI and machine studying work, and in response to a GitHub report, Python powers round 50% of all AI repositories. However as AI matures, extra builders are constructing on prime of the underlying mannequin slightly than coaching it. They’re constructing AI chatbots, RAG purposes, AI-powered SaaS instruments, and APIs that combine providers like OpenAI and Anthropic.
That is the place TypeScript shines. It’s the language of contemporary utility growth and is particularly suited to the complexities of AI integration. TypeScript has seen 77.9% year-over-year development in AI-tagged initiatives on GitHub, turning into the go-to language for constructing user-interactive interfaces and dashboards.
Begin studying TypeScript
Are you able to study the language that may outline the subsequent growth period? In case you already perceive JavaScript, be part of our free TypeScript studying course as we speak. Fully new to programming? Begin by studying JavaScript. TypeScript is a superset of JavaScript, so that you want a stable basis in variables, capabilities, objects, and arrays earlier than leveling as much as TypeScript.
If you wish to study finest from actual instructors in structured periods, take a look at our stay digital bootcamp. A lot of our bootcamps concentrate on constructing with AI instruments. For instance, our upcoming Full Stack Improvement with AI for Newcomers bootcamp makes use of TypeScript and AI-assisted workflows when constructing initiatives.
In case you’re serious about TypeScript and AI, do not forget that Codecademy has loads of programs and sources that can assist you get conversant in different common AI instruments as nicely. Whether or not you wish to get hands-on with machine studying frameworks or check out new APIs, our platform makes it simple to sharpen your expertise and prepare to construct smarter, extra inventive apps for the longer term.
