IE 11 supported?

Is nano-memoize supported on IE11?

I am trying to use Nano-memoize in my web application which also uses Typescript and Webpack to transpile the code to ES5. However the webpage simply fails to load in IE 11. It works in Chrome.

I have followed the following steps:

• npm install nano-memoize
• added import 'nano-memoize/browser/nano-memoize' to my source file.
• memoized a function like const memoizedFunc = nanomemoize(myFunc)

(the web application is based on create-react-app but the memoized function is not directly used in React components).

@KiranMohan I have not tried that combination of options. However, I just ran some quick tests. IE11 does not support Object.assign which is used by nano-memoize and comes through on a Babel ES5 transpile so is likely to come through on webpack also. There is a polyfill here https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign You might be able to configure webpack to pull something like this in.

@KiranMohan I just pushed v1.1.6 with a test for ie11. All unit tests pass so long as the polyfill for Object.assign is provided.

@anywhichway Figured out the root cause of my issue. See details here https://stackoverflow.com/questions/57968410/webpack-how-to-transpile-code-in-node-modules

I think transpiling nano-memoize might help other users avoid this issue.

And thank you for this awesome library. 👍

@KiranMohan Thanks for the compliment. I just pushed v1.1.7 to Github (but not to NPM yet). I re-worked it by hand so it is fully compatible with IE 11 in order to keep the size down and the speed up. Take a look and tell me what you think.

@KiranMohan I am closing this so there are not lingering open issues. Re-open if you have a concern.
