TypeScript Best Practices for 2025

TypeScript has become the standard for building large-scale JavaScript applications. Here are the best practices you should follow in 2025.

Type Safety First

Always prefer strict type checking and avoid using `any` whenever possible.

// Good

function greet(name: string): string {

return `Hello, ${name}!`

}

// Avoid

function greet(name: any): any {

return `Hello, ${name}!`

}

Use Type Inference

Let TypeScript infer types when possible to keep your code clean and maintainable.

Conclusion

Following these best practices will help you write better TypeScript code that's easier to maintain and scale.
