Description: Isolated modules in TypeScript are a feature that allows TypeScript files to be treated as separate modules, enhancing encapsulation and code organization. This functionality is based on the use of the ‘export’ keyword to expose variables, functions, or classes from a file, and ‘import’ to use them in other files. By treating each file as a module, it prevents pollution of the global namespace, reducing the risk of conflicts between different parts of the code. Additionally, isolated modules facilitate code reuse and collaboration in large projects, as each developer can work on specific modules without interfering with others’ work. This feature also allows for better dependency management and a clearer project structure, resulting in more maintainable and scalable code. In summary, isolated modules are fundamental to modern programming in TypeScript, promoting good development practices and a more robust software architecture.
