TypeScript Best Practices
Essential patterns and practices for writing better TypeScript code.
TypeScript has become the de facto standard for large-scale JavaScript applications. However, using TypeScript effectively requires understanding its features and adopting best practices.
Type Safety vs Type Complexity
While TypeScript's type system is powerful, it's important to find the right balance. Overly complex types can make code harder to understand and maintain. Focus on types that provide real value and clarity.
Leveraging Type Inference
TypeScript's type inference is remarkably good. Let the compiler infer types when possible, and only add explicit type annotations when they improve code clarity or catch potential errors.
Utility Types and Generics
Master TypeScript's built-in utility types like Partial, Pick, and Omit. Learn to write effective generic types that are reusable and flexible. These tools can significantly reduce code duplication and improve type safety.
