Error "SCRIPT 1028 Expected identifier, string or number" with IE11

Hello,

first thanks for this library which was especially helpful for merging objects. 😃

The issue I have is with IE11 which does not seem to like the name of some functions like get in get(obj, path, value) and generate the classic error:

SCRIPT 1028 Expected identifier, string or number

Yet I’m using a whole bunch of transpilation tools to be sure the generated code is compatible with older browsers:

browserify --extension=.jsx --transform [babelify --presets=es2015,stage-2,react --plugins=[babel-plugin-transform-es3-member-expression-literals,babel-plugin-transform-es3-property-literals]] --transform [es3ify] GUI/index.jsx --outfile dist/GUI/bundle.js

But as far as I understand the tools consider your code as valid, which it is for most browsers indeed.

Have you ever heard about this issue?

Thanks.

Hello, FYI I have finally fixed it by hand by pre-generating a transpiled version of dot-prop. package.json:

"scripts": {
    "precompile": "babel node_modules/dot-prop/index.js --out-file precompiled/dot-prop.js",

And referencing it in place of the original package stored in node_modules. someModule.js:

const dotProp = require("../precompiled/dot-prop");

Hopefully it will help someone else. 😃

I agree this is not a perfect solution, and I would not scale it to dozens of modules. But for my use-case this is a pragmatic workaround that has unblocked IE 11 support. As for Webpack I’ve tried it and unfortunately it comes with its own set of issues and bugs so I will wait for it to be ready for prime-time. I’ll post any better solution, stay tuned… 😃
