Hello,
I'm looking for the correct way to enable polyfill for IE10 to support ES6 syntax.
I'm using fetch to make call an api and getting this error on IE10:
jQuery.Deferred exception: 'fetch' is undefinedReferenceError: 'fetch' is undefined

Thank you!!

Not a maintainer here, but you probably want to use something like whatwg-fetch to polyfill window.fetch which isn't supported in IE. It is intentionally not included in babel-polyfill.

Hope that helps!

@farissi quick background: task-config's javascripts.babel or javascripts.babelLoder.options is used as the babelLoader options in the Webpack config.

For general IE10 support, you should be able to use targets ie 10 as documented at https://babeljs.io/docs/en/babel-preset-env

Note the IE10 limitations in https://babeljs.io/docs/en/caveats

For window.fetch you might also check out https://github.com/github/fetch, recommended by zloirock the core-js maintainer. I haven't used fetch or whatwg-fetch.

Closing because this seems to not be a Blendid issue, but 👍 feel free to reopen if I'm wrong about that!
