Introduction
TypeScript has become the de facto standard for building large-scale JavaScript applications. In this comprehensive guide, we'll explore the best practices that will make your TypeScript code more maintainable and robust.
Use Strict Mode
Always enable strict mode in your tsconfig.json. This catches common errors at compile time and enforces better coding practices. The strict flag enables all strict type-checking options.
Avoid Using Any
The any type defeats the purpose of TypeScript. Instead, use unknown for truly unknown types, or take the time to define proper interfaces and types for your data structures.
Leverage Type Inference
TypeScript's type inference is powerful. You don't need to explicitly type everything - let TypeScript infer types where it makes sense, making your code cleaner and more readable.
