Firstly, code organization is crucial. I advocate for a modular structure where functionality is grouped logically. This means separating your code into distinct layers such as components, services, utilities, and models. For instance, in a Frontend Developer role, components could be further categorized into UI elements, pages, and layouts. This approach not only makes the codebase more navigable but also enhances reusability and testability. Adopting a feature-based directory structure can be particularly beneficial, where all related files for a feature are grouped together. This makes it easier to manage and understand the code as the project scales.
Regarding managing types, leveraging TypeScript’s powerful type system effectively is key. I ensure that all custom types and interfaces are placed in dedicated files and, whenever possible, are grouped by domain context. This practice makes...
