Description: The ‘Strict’ mode in TypeScript is a configuration that enables stricter type-checking options during application development. This mode is activated through the ‘strict’ option in the ‘tsconfig.json’ configuration file. By enabling ‘Strict’, TypeScript applies a series of rules that help detect potential errors in the code, thus promoting greater safety and robustness in applications. Among the features activated by this mode are strict null checks, assignment checks, and implicit type restrictions, among others. This means that developers must be more explicit in defining types and manipulating data, which can result in cleaner and more maintainable code. The adoption of ‘Strict’ mode is especially recommended in larger projects or those where collaboration among multiple developers is common, as it helps prevent errors that could be difficult to trace in less strict code. In summary, ‘Strict’ mode not only improves code quality but also encourages better programming practices within the TypeScript ecosystem.
