10 | * **Note:** This method can't reliably detect native functions in the presence
|
---|
11 | * of the core-js package because core-js circumvents this kind of detection.
|
---|
12 | * Despite multiple requests, the core-js maintainer has made it clear: any
|
---|
13 | * attempt to fix the detection will be obstructed. As a result, we're left
|
---|
14 | * with little choice but to throw an error. Unfortunately, this also affects
|
---|
15 | * packages, like [babel-polyfill](https://www.npmjs.com/package/babel-polyfill),
|
---|
16 | * which rely on core-js.
