Hey guys, What would it take to get block scoped prototype extensions into JavaScript? I’m curious to get some thoughts before I write a proposal.
The use case is similar to Scala’s block scoped implicits. In my application code I want Array.prototype.indexOf to return an Option<number>, rather than number | -1. If I patch Array’s prototype directly, it will break other libraries in my project. It would be nice to have a way to extend the prototype for just a block, or just a file. Would a combination of block-scoped imports (maybe dynamic imports, to patch the prototype) and some sort of onExitBlock hook (to unpatch the prototype) be enough to implement this? Has anyone else thought about this sort of feature? Boris _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
