TypeScript Best Practices
TypeScript adds type safety to JavaScript, helping you catch errors early and write more reliable code.
Best Practice 1: Use Strict Mode
Enable strict mode in `tsconfig.json`:
```json
{
"compilerOptions": {
"strict": true
}
}
```
Best Practice 2: Define Interfaces for Objects
Use interfaces to define the shape of objects:
```typescript
interface User {
id: number;
name: string;
email: string;
}
function getUser(id: number): User {
// implementation
}
```
Best Practice 3: Avoid `any` Type
Always specify types instead of using `any`:
```typescript
// ❌ Avoid
function process(data: any) {}
// ✅ Better
function process(data: unknown) {}
```
Conclusion
Follow these practices to write cleaner, safer TypeScript code!
