Version Details and Security Vulnerabilities

Based on the provided data, there's no information available about the previous stable version of the tslib package to compare against version 1.0.0. Therefore, a comparison between the two versions is impossible. However, focusing solely on tslib version 1.0.0, it's a foundational runtime library crucial for TypeScript projects. It provides essential helper functions needed to execute compiled TypeScript code in JavaScript environments. These helpers are designed to seamlessly support language features like inheritance, async/await, and decorators, ensuring compatibility and proper functionality when TypeScript's higher-level constructs are translated into plain JavaScript.

For developers using TypeScript, tslib is often automatically included as a dependency when compiling TypeScript projects. Its primary role is to abstract away the complexities of cross-browser compatibility and different JavaScript engine implementations, providing a reliable and consistent runtime environment for TypeScript applications. Because it handles low-level code, developers don't typically interact with tslib directly. Instead, it works silently in the background, enabling TypeScript features to function correctly in the browser or Node.js environment. Understanding that such support library exists is important when debugging your code and is useful to know that for legacy projects of Typescript it might be necessary to upgrade this dependency from time to time. The library's small size and focused purpose contribute to its efficiency, minimizing the overall impact on application performance.
