Thank you for showing me the bigger picture. If there ever come a day when web/stdlib APIs are exposed as modules, then polyfills are themselves modules.
But if modules aren’t supposed to patch the runtime as effectible scripts do, then I have the same question as Kyle does, what’s the use case for importing a module without binding it to an identifier? > On Mar 17, 2015, at 12:37 AM, caridy <[email protected]> wrote: > > inline > >> On Mar 16, 2015, at 2:21 AM, Glen Huang <[email protected]> wrote: >> >> On second thought, this does seem to imply that polyfills can’t use the >> module syntax, which means they can’t use utility libraries written in >> module syntax, and, if you are writing a complex polyfill, managing >> dependencies requires ensuring correct script loading order (whether that >> means managing script element order or file concatenating order in a build >> step).
