Object doesn't support property or method 'startsWith'

Question

In my webpack:

{
  "presets": [
    ["env", {
      "targets": {
        "browsers": [">0.1%", "last 4 versions", "not ie <= 9"]
      }
    }]
  ]
}

But I have an error in IE:

Object doesn't support property or method 'startsWith'

startsWith is a method of String, 'hello there'.startsWith('hello') === true. It's not supported in any version of IE, but you can polyfill it. polyfill.io is great at catching a lot of this stuff with zero effort.
