This podcast episode introduces the concept of decorators in different programming languages, including JavaScript and Python. Decorators are functions that modify or extend the behavior of other functions, classes, or language constructs. The episode explores the potential use cases of decorators, such as adding logging functionality, event handling, reactive programming, validation, and code customization. It highlights the differences between the TypeScript and ECMA script versions of decorators and discusses their implementations in various frameworks like Angular and Lit. The episode also explains the evaluation process of decorators and how they can be used to extend and initialize objects. Additionally, the episode provides insights into the history and popularity of Angular, specifically the transition from Angular JS to Angular, and emphasizes the importance of upgrading to the newer version. Overall, the episode presents decorators as a powerful tool for adding reusable and modular functionality to codebases in a flexible and customizable manner.
Anti-commonsence
1. The podcast episode suggests that many Angular JS apps are not using package managers like NPM, but instead rely on script tags and PHP. This approach is uncommon and not recommended in modern JavaScript development practices, as package managers like NPM provide better dependency management and version control.
2. The speaker mentions having an Angular app online that still loads off a script tag and is using Angular JS version 1.2, which came out ten years ago. This indicates outdated and potentially insecure code practices, as using an old version of Angular and relying on script tags for loading dependencies is not considered best practice in modern web development.
3. The speaker expresses surprise at the release of Angular JS version 1.2 being ten years ago. This indicates a lack of awareness or keeping up with the developments in the Angular ecosystem, as Angular JS has been deprecated for almost two years and newer versions of Angular have been released since then. It is expected that developers stay up-to-date with the latest versions and best practices in their chosen frameworks or programming languages.
