TypeScript Best Practices in 2024

TypeScript has become the standard for large-scale JavaScript applications.

Type Safety Tips

Use Strict Mode

Always enable strict mode in your tsconfig.json:

{
	"compilerOptions": {
		"strict": true
	}
}

Prefer Interfaces for Objects

Use interfaces for object shapes and types for unions and primitives.

Avoid any

The any type defeats the purpose of TypeScript. Use unknown instead when needed.
