TS Home
TypeScript Home” — what people usually mean when they say that phrase.
“TypeScript Home” = the official TypeScript website → https://www.typescriptlang.org
It is the central, official, most trustworthy place to learn about TypeScript, get the latest version, read documentation, try examples, see what’s new, download tools, etc.
Let me walk you through it like we’re opening the website together right now.
1. What you see when you first open https://www.typescriptlang.org
The homepage has several very important sections (as of 2025–2026):
|
0 1 2 3 4 5 6 7 8 9 |
[Big hero section] TypeScript — JavaScript with syntax for types. TypeScript is JavaScript with an optional type layer. Strongly typed, but still JavaScript. |
Right below usually you see big colorful buttons:
- Try TypeScript → opens the online playground
- Download → links to install TypeScript (via npm or other ways)
- Documentation → the most important link for learning
- What’s new in 5.8 / 5.9 / … → latest features
2. Most important parts of the TypeScript Home (the ones you will use most)
| Section on homepage | What it really is | When / why you go there |
|---|---|---|
| Playground | Online TypeScript editor + JavaScript output | Quick experiments, trying new syntax, sharing code |
| Documentation | The official handbook + reference | Learning TypeScript, looking up syntax, deep dives |
| Handbook | The best beginner → intermediate guide | Most people start here |
| Download / Install | How to add TypeScript to your project | When setting up a real project |
| What’s New | Release notes of latest version | Checking new features, breaking changes |
| TS Config Reference | Every possible tsconfig.json setting explained | When configuring strictness, module system, etc |
| Declaration Files (.d.ts) | Info about @types / DefinitelyTyped | When using JavaScript libraries in TypeScript |
| Migrating from JavaScript | Guide for adding types gradually | Converting old JS project to TS |
| TypeScript for … | React / Node.js / Vue / Angular / Deno / etc | Framework-specific TypeScript advice |
3. The most visited page: The TypeScript Handbook
Link: https://www.typescriptlang.org/docs/handbook/introduction.html
This is divided into two main tracks:
A. The Handbook (recommended learning path) Covers almost everything a typical developer needs:
- The Basics
- Everyday Types
- Narrowing
- Functions
- Object Types
- Generics
- Classes
- Modules
- Utility Types
- Decorators (newer versions)
- JSX / React support
- …
B. Reference (more like a dictionary/encyclopedia) Very detailed, used when you want to understand exactly how something works:
- Type Inference
- Type Compatibility
- Advanced Types
- Conditional Types
- Mapped Types
- Template Literal Types
- Declaration Merging
- …
Teacher tip: Most people start with the Handbook → read the first 10–15 chapters carefully Later they only go to Reference when they meet something confusing or very advanced.
4. The Playground – your best friend when learning
https://www.typescriptlang.org/play
Features that make it extremely useful:
- You can write TypeScript on the left
- See JavaScript output on the right
- See red error messages instantly
- Change TypeScript version (4.9, 5.0, 5.4, 5.5, 5.6, … latest nightly)
- Change target (ES5, ES2022, ESNext…)
- Change strictness / module system
- Share link with your code (very useful when asking for help)
- Many examples in the left sidebar (very good for learning)
Very useful trick:
At the bottom of the playground there is a “TS Config” button → you can turn almost all strict options on/off and immediately see how the errors change.
5. Quick comparison: where should you go for different needs?
You want to… → Go to this part of typescriptlang.org
- Just try TypeScript quickly → Playground
- Learn TypeScript from zero → Handbook → “The Basics” chapter
- Understand a difficult type error → Handbook + Reference
- See latest features & changes → What’s New / Release Notes
- Add TypeScript to existing project → Download + TSConfig Reference
- Use React with TypeScript → Documentation → React
- Find type definitions for a library → DefinitelyTyped (linked from home)
- Report bug / see roadmap → GitHub repo (also linked from home)
6. Real example: how most people use “TypeScript Home” in practice
Day 1 → Open https://www.typescriptlang.org/play → Try basic types, interfaces, unions, generics from Handbook examples
Day 3–7 → Read Handbook chapters 1–12 slowly → Copy-paste examples into playground → Change them → see what breaks and why
Week 2 → Create real project → Go to https://www.typescriptlang.org → Download → Run npm install -D typescript → Run npx tsc –init → Go back to site → TSConfig Reference → choose good settings
Month 2 → Meet weird error Type ‘A’ is not assignable to type ‘B’ → Search in Handbook “Narrowing” + “Type Guards” + “Type Predicates”
Month 3+ → Go to “What’s New” to see new features like satisfies, const type parameters, improved inference, etc.
Summary – in one sentence each
- TypeScript Home = https://www.typescriptlang.org
- It is the official house of TypeScript
- Contains playground, handbook, reference, release notes, installation
- Best place for learning, reference, trying new versions, finding framework guides
Would you like me to walk you through one specific part in much more detail? For example:
- Open the playground together and try 10 small examples
- Go through the first 5 chapters of the Handbook slowly
- Explain the most important tsconfig.json settings
- Show new features from TypeScript 5.4 / 5.5 / 5.6
Just tell me which direction you want to go next! 😄
