Babel compiled ES5 doesn't work in IE11

Babel compiled ES5 doesn’t work in IE11

Current Behavior I compiled my ES6 code with babel and Webpack and it doesn’t work in Internet Explorer browser.

Input Code http://iml.ru/new-widget

And I receive such Error in console: Syntax Error on in /js/newPvz-compiled.js line 37

Expected behavior/code

It should work in IE

Babel Configuration (.babelrc, package.json, cli command)

.babelrc

{
  "presets": [
    ["env", {
      "targets": {
        "browsers": ["last 2 versions", "ie >= 11"]
      },
        "useBuiltIns": true
    }],

  ]
}

package.json

{
  "scripts": {
    "minify": "node minify.js"
  },
  "dependencies": {
    "babel-cli": "^6.26.0",
    "babel-preset-es2015": "^6.24.1",
    "less": "^3.0.1",
    "minifier": "0.8.1",
    "vue2-filters": "^0.3.0",
    "watch": "^1.0.2",
    "webpack": "^4.6.0",
    "babel-polyfill": "6.26.0",
    "babel-preset-es2015-ie": "6.7.0"
  },
  "devDependencies": {
    "babel-preset-env": "^1.7.0"
  }
}

cli

$ webpack
$ ./babel-cli/bin/babel.js --presets babel-preset-es2015-ie /js/newPvz-webpack.js  -o /js/newPvz-compiled.js

Environment

• Babel version(s): babel-1.4.0
• Node/npm version: v4.2.6
• OS: Windows 10
• Monorepo [e.g. yes/no/Lerna]
• cli

Possible Solution I tried to add babel-preset-es2015 and configure IE as supported browsers in .babelrc

I’m sorry, this problem is not related to Babel. I found the solution. Had to add devtools to webpack.config to remove eval

const path = require('path');
module.exports = {
  devtool: "source-map",
  entry: ['babel-polyfill', path.resolve(__dirname, './yourjs.js')],
  mode: 'production',
  output: {
    path: __dirname+'/draft.iml.ru/static/main/js/',
    filename: 'yout.js'
  }
};

You can close this issue.

IE11 does not recognize let

That’s not what the docs say: https://docs.microsoft.com/en-us/scripting/javascript/reference/let-statement-javascript
