javascript - Create annotation with babel ES6 - Stack Overflow

I m actually developping an application using babeljs and ES6 (with .js files) and I was wondering if it was possible to create annotations, like we can do with typescript, using babeljs and ES6 ?

• There are no annotations or decorators in ES6. Babel may support some experimental features though. – Bergi Commented Jul 29, 2015 at 13:59
• What do you mean by "experimental features" ? I tried it and it seems to work as I expect. I should not use it in production environnment ? – mfrachet Commented Jul 30, 2015 at 9:26
• Yes, decorators are an experimental feature – Bergi Commented Jul 30, 2015 at 12:00
• So I should not use this in production environnement ? – mfrachet Commented Jul 30, 2015 at 12:04
• Rather not I'd say. From that page: "use with extreme caution. Babel may update without warning in order to track spec changes.". You'll have to decide yourself if you want to live with that. – Bergi Commented Jul 30, 2015 at 12:07

JavaScript doesn't have a construct identical to TypeScript annotations (all kinds of them). There is however a proposal for Decorators for ES7, and BabelJS does implement that (With the appropriate configuration). Here's a nice article describing the differences between the two.
