What it does

Proposal-decorators is a tool that provides decorators for ES6 classes, allowing developers to modify or extend the behavior of classes in a declarative way.

When to use it

•When you need to add logging or authentication to multiple classes in your application
•When you want to implement aspect-oriented programming in your JavaScript project
•When you need to modify the behavior of third-party classes without changing their source code

Ready-to-paste prompt

@loggingDecorator class User { @loggingDecorator sayHello() { console.log('Hello'); } }

Heads up: Make sure to use the `legacy` option when installing the `@babel/plugin-proposal-decorators` plugin, as the default behavior has changed in recent versions, by adding `--legacy-peer-deps` to your install command
